      Por que escolher um DPCV?<\/h2>\r\n\r\n\r\n\r\n\r\nCom um DPCV instalado em seu sistema, voc\u00ea obter\u00e1 redu\u00e7\u00e3o no consumo de energia, evitar\u00e1 o risco de ru\u00eddos inc\u00f4modos e ter\u00e1 um processo de comissionamento simples.\r\n\r\n\r\n\r\n\r\n

      Como funciona um DPCV?<\/h2>\r\n\r\n\r\n\r\n\r\nUma DPCV inclui um diafragma, uma mola e um tubo capilar conectando a v\u00e1lvula parceira no tubo de alimenta\u00e7\u00e3o e a v\u00e1lvula DPCV no tubo de retorno para controlar a perda de press\u00e3o do circuito.\r\n\r\n\r\n\r\n\r\n\r\nA v\u00e1lvula de controle de press\u00e3o diferencial (DPCV) \u00e9 um tipo especial de v\u00e1lvula de controle cuja a\u00e7\u00e3o est\u00e1 relacionada a uma diferen\u00e7a de press\u00e3o medida. Na pr\u00e1tica, o DPCV \u00e9 utilizado em diversas aplica\u00e7\u00f5es, como ser\u00e1 explicado mais adiante, basicamente, seu objetivo \u00e9 manter uma diferen\u00e7a de press\u00e3o constante em uma determinada parte da rede hidr\u00e1ulica. Dentro do DPCV, duas cavidades s\u00e3o separadas por meio de uma membrana. Uma cavidade est\u00e1 conectada internamente ao lado a montante da DPCV enquanto a outra est\u00e1 conectada a um local remoto por meio de um pequeno tubo capilar. Desta forma, a press\u00e3o diferencial atrav\u00e9s da membrana \u00e9 igual \u00e0 diferen\u00e7a de press\u00e3o entre o ponto de medi\u00e7\u00e3o a montante e o DPCV. O deslocamento resultante do fuso depende do equil\u00edbrio de for\u00e7as entre a membrana e a mola.\r\n\r\n\r\n\r\n\r\n\r\n\u2022 Controle \u0394P\r\n\r\n\r\n\r\n\r\n\r\nO diafragma DPCV ir\u00e1 regular para controlar \u0394pC (press\u00e3o diferencial atrav\u00e9s do circuito) dependendo do impulso de press\u00e3o do lado da alimenta\u00e7\u00e3o e da press\u00e3o direta do lado de retorno. A for\u00e7a da mola ser\u00e1 igual ao \u0394pC.\r\n\r\n\r\n\r\n\r\n\r\nEm todas as DPCVs ZECO, o diafragma ser\u00e1 um diafragma rolante que resultar\u00e1 em um design de v\u00e1lvula muito compacto. Dependendo da v\u00e1lvula de controle de press\u00e3o diferencial ZECO selecionada, o \u0394pC pode ser fixo ou ajust\u00e1vel externamente.\r\n\r\n","link":"https:\/\/zecovalve.com\/pt\/tag\/dpcv","name":"DPCV","slug":"dpcv","taxonomy":"post_tag","meta":[],"yoast_head":"\nDPCV - Differential Pressure Control 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\/tag\/dpcv\" \/>\n<meta property=\"og:locale\" content=\"pt_PT\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"DPCV - Differential Pressure Control Valve | ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"To meet the growing use of variable speed pumps for HVAC applications, ZECO Fluid Systems has launched a range of Differential Pressure Control Valves (DPCV) specifically aimed at optimizing system performance. Extremely efficient, the DPCV is set to a maximum differential pressure which ensures flow cannot exceed the desired rate. It, therefore, helps reduce energy consumption, and the risk of noise and simplifies the commissioning process. GET DCPV VALVE PRICE What is DCPV? Differential 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. ZECO\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. What is Differential Pressure Control? A 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. Specifications of DPCV Nominal diameter: DN25 \u2013 DN50 Media temperature : -10\u00b0C to 120\u00b0C Pressure range: 16 bars- 25 bars Permissible medium\/application: Chilled\/hot water, Glycol solution, Cooling water Connection: Threaded BSP DPCV Nominal diameter: DN65 \u2013 DN250 Media temperature : -10\u00b0C to 120\u00b0C Pressure range: 16 bars -25 bars Permissible medium\/application: Chilled\/hot water, Glycol solution, Cooling water Connection: RF Why choose a DPCV? With a DPCV installed in Your system, You will achieve reduced energy consumption, avoid the risk of annoying noise and have a simple commissioning process. How does a DPCV Work? A 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. The 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. \u2022 \u0394P Control The 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. In 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.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/zecovalve.com\/pt\/tag\/dpcv\" \/>\n<meta property=\"og:site_name\" content=\"ZECO Valve\" \/>\n<meta property=\"og:image\" content=\"https:\/\/zecovalve.com\/wp-content\/uploads\/2022\/10\/DPCV-768x1024.jpg\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"WebSite\",\"@id\":\"https:\/\/zecovalve.com\/#website\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"ZECO Valve\",\"description\":\"Industrial Ball Valve, Gate Valve and Globe Valve Manufacturer\",\"potentialAction\":[{\"@type\":\"SearchAction\",\"target\":\"https:\/\/zecovalve.com\/?s={search_term_string}\",\"query-input\":\"required name=search_term_string\"}],\"inLanguage\":\"pt-PT\"},{\"@type\":\"CollectionPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/dpcv#webpage\",\"url\":\"https:\/\/zecovalve.com\/tag\/dpcv\",\"name\":\"DPCV - Differential Pressure Control Valve | ZECO Valve\",\"isPartOf\":{\"@id\":\"https:\/\/zecovalve.com\/#website\"},\"breadcrumb\":{\"@id\":\"https:\/\/zecovalve.com\/tag\/dpcv#breadcrumb\"},\"inLanguage\":\"pt-PT\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/zecovalve.com\/tag\/dpcv\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/zecovalve.com\/tag\/dpcv#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"item\":{\"@type\":\"WebPage\",\"@id\":\"https:\/\/zecovalve.com\/\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"Home\"}},{\"@type\":\"ListItem\",\"position\":2,\"item\":{\"@type\":\"WebPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/dpcv\",\"url\":\"https:\/\/zecovalve.com\/tag\/dpcv\",\"name\":\"DPCV\"}}]}]}<\/script>\n<!-- \/ Yoast SEO Premium plugin. -->","_links":{"self":[{"href":"https:\/\/zecovalve.com\/pt\/wp-json\/wp\/v2\/tags\/2560","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zecovalve.com\/pt\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/zecovalve.com\/pt\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/zecovalve.com\/pt\/wp-json\/wp\/v2\/posts?tags=2560"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
