It, therefore, helps reduce energy consumption, and the risk of noise and simplifies the commissioning process.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nGET DCPV VALVE PRICE<\/strong><\/a>\r\n\r\n\r\n\r\n\r\nWhat 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

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"}],"taxonomy_info":{"category":[{"value":1,"label":"Uncategorized"}],"post_tag":[{"value":2560,"label":"DPCV"}]},"yoast_head":"\n
