In practice, the DPCV is used in several applications as will be further explained basically, its goal is to maintain a constant pressure difference across a certain part of the hydraulic network. Inside the DPCV, two cavities are separated by means of a membrane. One cavity is internally connected to the upstream side of the DPCV while the other one is connected to a remote location by means of a small capillary pipe. This way, the differential pressure across the membrane equals the pressure difference between the upstream measuring point and the DPCV. The resulting spindle travel depends on the force balance between the membrane and the spring.\r\n\r\n\r\n\r\n\r\n\r\n\u2022 \u0394P Control\r\n\r\n\r\n\r\n\r\n\r\nThe DPCV diaphragm will regulate to control \u0394pC (differential pressure across the circuit) depending on pressure impulse from the supply side and direct pressure from the return side. The spring force will equal the \u0394pC.\r\n\r\n\r\n\r\n\r\n\r\nIn all ZECO DPCVs, the diaphragm will be a rolling diaphragm which will result in a very compact valve design. Depending on the ZECO Differential Pressure Control Valve selected, \u0394pC may be fixed or externally adjustable.\r\n\r\n","parent":0,"count":12,"filter":"raw"},{"term_id":2452,"name":"dynamic balancing valve","slug":"dynamic-balancing-valve","term_group":0,"term_taxonomy_id":2452,"taxonomy":"post_tag","description":"","parent":0,"count":4,"filter":"raw"},{"term_id":3505,"name":"dynamic balancing valves","slug":"dynamic-balancing-valves","term_group":0,"term_taxonomy_id":3505,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3508,"name":"dynamic flow balancing","slug":"dynamic-flow-balancing","term_group":0,"term_taxonomy_id":3508,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":2525,"name":"PICV","slug":"picv","term_group":0,"term_taxonomy_id":2525,"taxonomy":"post_tag","description":"","parent":0,"count":4,"filter":"raw"},{"term_id":2524,"name":"Pressure independent Control Valve","slug":"pressure-independent-control-valve","term_group":0,"term_taxonomy_id":2524,"taxonomy":"post_tag","description":"","parent":0,"count":6,"filter":"raw"},{"term_id":2750,"name":"Valves for Industrial Cooling Towers","slug":"valves-for-industrial-cooling-towers","term_group":0,"term_taxonomy_id":2750,"taxonomy":"post_tag","description":"\r\n\r\nGET COOLING TOWER VALVES PRICE<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n\r\n\r\nWhat is a Cooling Tower?<\/h2>\r\n\r\n\r\n\r\n\r\nA cooling tower is a big vessel that contains a large fan blowing air through the unit.

<\/figure>\r\n\r\n\r\n\r\nWhy choose a DPCV?<\/h2>\r\n\r\n\r\n\r\n\r\nWith a DPCV installed in Your system, You will achieve reduced energy consumption, avoid the risk of annoying noise and have a simple commissioning process.\r\n\r\n\r\n\r\n\r\nHow does a DPCV Work?<\/h2>\r\n\r\n\r\n\r\n\r\nA DPCV includes a diaphragm, a spring, and a capillary tube connecting the partner valve in the supply pipe and the DPCV valve in the return pipe to control the circuit pressure loss.\r\n\r\n\r\n\r\n\r\n\r\nThe differential pressure control valve (DPCV) is a special kind of control valve whose action is related to a measured pressure difference. In practice, the DPCV is used in several applications as will be further explained basically, its goal is to maintain a constant pressure difference across a certain part of the hydraulic network. Inside the DPCV, two cavities are separated by means of a membrane. One cavity is internally connected to the upstream side of the DPCV while the other one is connected to a remote location by means of a small capillary pipe. This way, the differential pressure across the membrane equals the pressure difference between the upstream measuring point and the DPCV. The resulting spindle travel depends on the force balance between the membrane and the spring.\r\n\r\n\r\n\r\n\r\n\r\n\u2022 \u0394P Control\r\n\r\n\r\n\r\n\r\n\r\nThe DPCV diaphragm will regulate to control \u0394pC (differential pressure across the circuit) depending on pressure impulse from the supply side and direct pressure from the return side. The spring force will equal the \u0394pC.\r\n\r\n\r\n\r\n\r\n\r\nIn all ZECO DPCVs, the diaphragm will be a rolling diaphragm which will result in a very compact valve design. Depending on the ZECO Differential Pressure Control Valve selected, \u0394pC may be fixed or externally adjustable.\r\n\r\n","parent":0,"count":12,"filter":"raw"},{"term_id":2452,"name":"dynamic balancing valve","slug":"dynamic-balancing-valve","term_group":0,"term_taxonomy_id":2452,"taxonomy":"post_tag","description":"","parent":0,"count":4,"filter":"raw"},{"term_id":3505,"name":"dynamic balancing valves","slug":"dynamic-balancing-valves","term_group":0,"term_taxonomy_id":3505,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3508,"name":"dynamic flow balancing","slug":"dynamic-flow-balancing","term_group":0,"term_taxonomy_id":3508,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":2525,"name":"PICV","slug":"picv","term_group":0,"term_taxonomy_id":2525,"taxonomy":"post_tag","description":"","parent":0,"count":4,"filter":"raw"},{"term_id":2524,"name":"Pressure independent Control Valve","slug":"pressure-independent-control-valve","term_group":0,"term_taxonomy_id":2524,"taxonomy":"post_tag","description":"","parent":0,"count":6,"filter":"raw"},{"term_id":2750,"name":"Valves for Industrial Cooling Towers","slug":"valves-for-industrial-cooling-towers","term_group":0,"term_taxonomy_id":2750,"taxonomy":"post_tag","description":"\r\n\r\nGET COOLING TOWER VALVES PRICE<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n\r\n\r\nWhat is a Cooling Tower?<\/h2>\r\n\r\n\r\n\r\n\r\nA cooling tower is a big vessel that contains a large fan blowing air through the unit. Water including excess heat from the HVAC system is entered at the top of the cooling tower where the water flows down several flow plates to the cooling tower basin. As the water passes to the bottom, the air is pulled through the plates and over the water, and heat is withdrawn through evaporation. Hereafter the cold water to pump back into the HVAC system ready to collect more heat.\r\n\r\n\r\n\r\n\r\n\r\nLarge cooling towers are typically installed on power plants and other industrial facilities and smaller versions are often seen on rooftops of shopping centers, hospitals, and large commercial buildings providing cooling to the HVAC system.\r\n\r\n\r\n\r\n\r\nHow is a Cooling Tower Application Optimized?<\/h2>\r\n\r\n\r\n\r\n\r\nWith proper balance, a water-cooled cooling tower may reduce cooling costs to a minimum while still providing the required design load. FlowCon recommends the following solution for Cooling Tower installation:\r\n\r\n\r\n\r\n\r\n\r\n \t- Pressure Independent Control Valve (PICV)<\/li>\r\n \t
- Automatic Balancing Valve (ABV)<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
What Types of Cooling Tower Valves are There?<\/h2>\r\n\r\n\r\n\r\n\r\nThere are several types of cooling tower valves that perform specific tasks. The most common types of cooling tower valves are control valves, isolation valves, distribution valves, and electronic float valves. These valves are strategically placed throughout the cooling tower, allowing for the regulation and control of water flow to promote evaporation, allowing the water to cool.\r\n\r\n\r\n\r\n\r\nCooling Towers with Pressure Independent Control Valve<\/a><\/strong> (PICV)<\/h2>\r\n\r\n\r\n\r\n\r\nThe PICV will react to system pressure changes and regulate the flow of water to the required flow by adjusting the actuator position. This helps the system to be accurately controlled even with pressure changes and reduced loads.\r\n\r\n\r\n\r\n\r\n<\/figure>\r\n\r\n\r\n\r\nCooling Towers with Automatic Balancing Valve<\/a><\/strong> (ABV)<\/h2>\r\n\r\n\r\n\r\n\r\nThe automatic balancing valve will react to system pressure changes and limit the flow of hot or cold water to the required max. flow helping the system to be accurately controlled even with pressure changes. This solution is recommended to be installed with a separate control valve.\r\n\r\n\r\n\r\n\r\n<\/figure>\r\n","parent":0,"count":7,"filter":"raw"}],"taxonomy_info":{"category":[{"value":2447,"label":"Balancing Valve"}],"post_tag":[{"value":2448,"label":"Balancing valve"},{"value":3506,"label":"balancing valve in hvac"},{"value":3507,"label":"balancing valve types"},{"value":2517,"label":"differential pressure control valve"},{"value":2560,"label":"DPCV"},{"value":2452,"label":"dynamic balancing valve"},{"value":3505,"label":"dynamic balancing valves"},{"value":3508,"label":"dynamic flow balancing"},{"value":2525,"label":"PICV"},{"value":2524,"label":"Pressure independent Control Valve"},{"value":2750,"label":"Valves for Industrial Cooling Towers"}]},"yoast_head":"\nBalancing Valve Types - PICV, DPCV, Static Balancing Valve | ZECO Valve<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/zecovalve.com\/pt\/classification-of-balancing-valves.html\" \/>\n<meta property=\"og:locale\" content=\"pt_PT\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Balancing Valve Types - PICV, DPCV, Static Balancing Valve | ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"The common types of balancing valves in HVAC systems are mainly static hydraulic balancing valves for eliminating static hydraulic imbalance and realizing ...

In practice, the DPCV is used in several applications as will be further explained basically, its goal is to maintain a constant pressure difference across a certain part of the hydraulic network. Inside the DPCV, two cavities are separated by means of a membrane. One cavity is internally connected to the upstream side of the DPCV while the other one is connected to a remote location by means of a small capillary pipe. This way, the differential pressure across the membrane equals the pressure difference between the upstream measuring point and the DPCV. The resulting spindle travel depends on the force balance between the membrane and the spring.\r\n\r\n\r\n\r\n\r\n\r\n\u2022 \u0394P Control\r\n\r\n\r\n\r\n\r\n\r\nThe DPCV diaphragm will regulate to control \u0394pC (differential pressure across the circuit) depending on pressure impulse from the supply side and direct pressure from the return side. The spring force will equal the \u0394pC.\r\n\r\n\r\n\r\n\r\n\r\nIn all ZECO DPCVs, the diaphragm will be a rolling diaphragm which will result in a very compact valve design. Depending on the ZECO Differential Pressure Control Valve selected, \u0394pC may be fixed or externally adjustable.\r\n\r\n","parent":0,"count":12,"filter":"raw"},{"term_id":2452,"name":"dynamic balancing valve","slug":"dynamic-balancing-valve","term_group":0,"term_taxonomy_id":2452,"taxonomy":"post_tag","description":"","parent":0,"count":4,"filter":"raw"},{"term_id":3505,"name":"dynamic balancing valves","slug":"dynamic-balancing-valves","term_group":0,"term_taxonomy_id":3505,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3508,"name":"dynamic flow balancing","slug":"dynamic-flow-balancing","term_group":0,"term_taxonomy_id":3508,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":2525,"name":"PICV","slug":"picv","term_group":0,"term_taxonomy_id":2525,"taxonomy":"post_tag","description":"","parent":0,"count":4,"filter":"raw"},{"term_id":2524,"name":"Pressure independent Control Valve","slug":"pressure-independent-control-valve","term_group":0,"term_taxonomy_id":2524,"taxonomy":"post_tag","description":"","parent":0,"count":6,"filter":"raw"},{"term_id":2750,"name":"Valves for Industrial Cooling Towers","slug":"valves-for-industrial-cooling-towers","term_group":0,"term_taxonomy_id":2750,"taxonomy":"post_tag","description":"\r\n\r\nGET COOLING TOWER VALVES PRICE<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n\r\n\r\nWhat is a Cooling Tower?<\/h2>\r\n\r\n\r\n\r\n\r\nA cooling tower is a big vessel that contains a large fan blowing air through the unit. Water including excess heat from the HVAC system is entered at the top of the cooling tower where the water flows down several flow plates to the cooling tower basin. As the water passes to the bottom, the air is pulled through the plates and over the water, and heat is withdrawn through evaporation. Hereafter the cold water to pump back into the HVAC system ready to collect more heat.\r\n\r\n\r\n\r\n\r\n\r\nLarge cooling towers are typically installed on power plants and other industrial facilities and smaller versions are often seen on rooftops of shopping centers, hospitals, and large commercial buildings providing cooling to the HVAC system.\r\n\r\n\r\n\r\n\r\nHow is a Cooling Tower Application Optimized?<\/h2>\r\n\r\n\r\n\r\n\r\nWith proper balance, a water-cooled cooling tower may reduce cooling costs to a minimum while still providing the required design load. FlowCon recommends the following solution for Cooling Tower installation:\r\n\r\n\r\n\r\n\r\n\r\n \t- Pressure Independent Control Valve (PICV)<\/li>\r\n \t

What Types of Cooling Tower Valves are There?<\/h2>\r\n\r\n\r\n\r\n\r\nThere are several types of cooling tower valves that perform specific tasks. The most common types of cooling tower valves are control valves, isolation valves, distribution valves, and electronic float valves. These valves are strategically placed throughout the cooling tower, allowing for the regulation and control of water flow to promote evaporation, allowing the water to cool.\r\n\r\n\r\n\r\n\r\nCooling Towers with Pressure Independent Control Valve<\/a><\/strong> (PICV)<\/h2>\r\n\r\n\r\n\r\n\r\nThe PICV will react to system pressure changes and regulate the flow of water to the required flow by adjusting the actuator position. This helps the system to be accurately controlled even with pressure changes and reduced loads.\r\n\r\n\r\n\r\n\r\n<\/figure>\r\n\r\n\r\n\r\nCooling Towers with Automatic Balancing Valve<\/a><\/strong> (ABV)<\/h2>\r\n\r\n\r\n\r\n\r\nThe automatic balancing valve will react to system pressure changes and limit the flow of hot or cold water to the required max. flow helping the system to be accurately controlled even with pressure changes. This solution is recommended to be installed with a separate control valve.\r\n\r\n\r\n\r\n\r\n<\/figure>\r\n","parent":0,"count":7,"filter":"raw"}],"taxonomy_info":{"category":[{"value":2447,"label":"Balancing Valve"}],"post_tag":[{"value":2448,"label":"Balancing valve"},{"value":3506,"label":"balancing valve in hvac"},{"value":3507,"label":"balancing valve types"},{"value":2517,"label":"differential pressure control valve"},{"value":2560,"label":"DPCV"},{"value":2452,"label":"dynamic balancing valve"},{"value":3505,"label":"dynamic balancing valves"},{"value":3508,"label":"dynamic flow balancing"},{"value":2525,"label":"PICV"},{"value":2524,"label":"Pressure independent Control Valve"},{"value":2750,"label":"Valves for Industrial Cooling Towers"}]},"yoast_head":"\nBalancing Valve Types - PICV, DPCV, Static Balancing Valve | ZECO Valve<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/zecovalve.com\/pt\/classification-of-balancing-valves.html\" \/>\n<meta property=\"og:locale\" content=\"pt_PT\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Balancing Valve Types - PICV, DPCV, Static Balancing Valve | ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"The common types of balancing valves in HVAC systems are mainly static hydraulic balancing valves for eliminating static hydraulic imbalance and realizing ...

What is DCPV?<\/h2>\r\n\r\n\r\n\r\n\r\nDifferential Pressure Control Valves - also commonly called DPCVs - are installed in heating or cooling systems to control sub-circuit pressure to a set or given maximum.\r\n\r\n\r\n\r\n\r\n\r\nZECO\u2019s DPCV range includes three different types. A type with pre-set \u0394pC (differential pressure across the circuit), a type with adjustable \u0394pC, and finally a type being a combined dynamic balancing valve and adjustable DPCV. They offer a flexible range meeting any system demand.\r\n\r\n\r\n\r\n\r\n
What is Differential Pressure Control?<\/h2>\r\n\r\n\r\n\r\n\r\nA differential pressure controller consists of a valve and a pressure actuator. Differential pressure controllers in the primary system are mainly used to keep a constant and lower differential pressure across a motorized control valve or a total system\/substation.\r\n\r\n\r\n\r\n\r\n

Why choose a DPCV?<\/h2>\r\n\r\n\r\n\r\n\r\nWith a DPCV installed in Your system, You will achieve reduced energy consumption, avoid the risk of annoying noise and have a simple commissioning process.\r\n\r\n\r\n\r\n\r\n
How does a DPCV Work?<\/h2>\r\n\r\n\r\n\r\n\r\nA DPCV includes a diaphragm, a spring, and a capillary tube connecting the partner valve in the supply pipe and the DPCV valve in the return pipe to control the circuit pressure loss.\r\n\r\n\r\n\r\n\r\n\r\nThe differential pressure control valve (DPCV) is a special kind of control valve whose action is related to a measured pressure difference. In practice, the DPCV is used in several applications as will be further explained basically, its goal is to maintain a constant pressure difference across a certain part of the hydraulic network. Inside the DPCV, two cavities are separated by means of a membrane. One cavity is internally connected to the upstream side of the DPCV while the other one is connected to a remote location by means of a small capillary pipe. This way, the differential pressure across the membrane equals the pressure difference between the upstream measuring point and the DPCV. The resulting spindle travel depends on the force balance between the membrane and the spring.\r\n\r\n\r\n\r\n\r\n\r\n\u2022 \u0394P Control\r\n\r\n\r\n\r\n\r\n\r\nThe DPCV diaphragm will regulate to control \u0394pC (differential pressure across the circuit) depending on pressure impulse from the supply side and direct pressure from the return side. The spring force will equal the \u0394pC.\r\n\r\n\r\n\r\n\r\n\r\nIn all ZECO DPCVs, the diaphragm will be a rolling diaphragm which will result in a very compact valve design. Depending on the ZECO Differential Pressure Control Valve selected, \u0394pC may be fixed or externally adjustable.\r\n\r\n","parent":0,"count":12,"filter":"raw"},{"term_id":2452,"name":"dynamic balancing valve","slug":"dynamic-balancing-valve","term_group":0,"term_taxonomy_id":2452,"taxonomy":"post_tag","description":"","parent":0,"count":4,"filter":"raw"},{"term_id":3505,"name":"dynamic balancing valves","slug":"dynamic-balancing-valves","term_group":0,"term_taxonomy_id":3505,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3508,"name":"dynamic flow balancing","slug":"dynamic-flow-balancing","term_group":0,"term_taxonomy_id":3508,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":2525,"name":"PICV","slug":"picv","term_group":0,"term_taxonomy_id":2525,"taxonomy":"post_tag","description":"","parent":0,"count":4,"filter":"raw"},{"term_id":2524,"name":"Pressure independent Control Valve","slug":"pressure-independent-control-valve","term_group":0,"term_taxonomy_id":2524,"taxonomy":"post_tag","description":"","parent":0,"count":6,"filter":"raw"},{"term_id":2750,"name":"Valves for Industrial Cooling Towers","slug":"valves-for-industrial-cooling-towers","term_group":0,"term_taxonomy_id":2750,"taxonomy":"post_tag","description":"\r\n\r\nGET COOLING TOWER VALVES PRICE<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n\r\n\r\n
What is a Cooling Tower?<\/h2>\r\n\r\n\r\n\r\n\r\nA cooling tower is a big vessel that contains a large fan blowing air through the unit. Water including excess heat from the HVAC system is entered at the top of the cooling tower where the water flows down several flow plates to the cooling tower basin. As the water passes to the bottom, the air is pulled through the plates and over the water, and heat is withdrawn through evaporation. Hereafter the cold water to pump back into the HVAC system ready to collect more heat.\r\n\r\n\r\n\r\n\r\n\r\nLarge cooling towers are typically installed on power plants and other industrial facilities and smaller versions are often seen on rooftops of shopping centers, hospitals, and large commercial buildings providing cooling to the HVAC system.\r\n\r\n\r\n\r\n\r\n
How is a Cooling Tower Application Optimized?<\/h2>\r\n\r\n\r\n\r\n\r\nWith proper balance, a water-cooled cooling tower may reduce cooling costs to a minimum while still providing the required design load. FlowCon recommends the following solution for Cooling Tower installation:\r\n\r\n\r\n\r\n\r\n

- Automatic Balancing Valve (ABV)<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
What Types of Cooling Tower Valves are There?<\/h2>\r\n\r\n\r\n\r\n\r\nThere are several types of cooling tower valves that perform specific tasks. The most common types of cooling tower valves are control valves, isolation valves, distribution valves, and electronic float valves. These valves are strategically placed throughout the cooling tower, allowing for the regulation and control of water flow to promote evaporation, allowing the water to cool.\r\n\r\n\r\n\r\n\r\n
Cooling Towers with Pressure Independent Control Valve<\/a><\/strong> (PICV)<\/h2>\r\n\r\n\r\n\r\n\r\nThe PICV will react to system pressure changes and regulate the flow of water to the required flow by adjusting the actuator position. This helps the system to be accurately controlled even with pressure changes and reduced loads.\r\n\r\n\r\n\r\n\r\n
<\/figure>\r\n\r\n\r\n\r\nCooling Towers with Automatic Balancing Valve<\/a><\/strong> (ABV)<\/h2>\r\n\r\n\r\n\r\n\r\nThe automatic balancing valve will react to system pressure changes and limit the flow of hot or cold water to the required max. flow helping the system to be accurately controlled even with pressure changes. This solution is recommended to be installed with a separate control valve.\r\n\r\n\r\n\r\n\r\n
