Qu\u2019est-ce que le Spirax Sarco PRV\u00a0?<\/h2>\r\n\r\n\r\n\r\n\r\nLes syst\u00e8mes \u00e0 vapeur bien con\u00e7us produisent de la vapeur propre et s\u00e8che \u00e0 distribuer \u00e0 haute pression \u2013 la meilleure qualit\u00e9 de vapeur au moindre co\u00fbt. De la vapeur \u00e0 basse pression est g\u00e9n\u00e9ralement n\u00e9cessaire au point d\u2019utilisation. Un contr\u00f4le efficace n\u00e9cessite une vanne automatique capable de r\u00e9duire la pression de la vapeur avec pr\u00e9cision, fiabilit\u00e9 et \u00e0 un co\u00fbt adapt\u00e9 \u00e0 l'application.

Comment fonctionne le r\u00e9gulateur pilote 25P\u00a0?<\/h2>\r\n\r\n\r\n\r\n\r\nThe Spirax Sarco pilot-operated pressure regulator works by balancing the downstream pressure against a control spring. This modulates a small valve head over a seat (the pilot). The flow through this seat is directed, in turn, to the main valve diaphragm, where it\r\nmodulates the main valve.\r\n\r\n\r\n\r\n\r\n\r\nAfin d'obtenir les conditions de fonctionnement les plus stables, une conduite de d\u00e9tection de pression externe doit \u00eatre utilis\u00e9e. Cela permet \u00e0 la pression en aval de revenir vers la face inf\u00e9rieure du diaphragme pilote, \u00e9quilibrant la force du ressort et provoquant l'\u00e9tranglement de la vanne pilote. Cela stabilise la vanne pilote, permettant un d\u00e9bit constant \u00e0 travers la membrane principale. Cela garantit que la vanne principale est \u00e9galement r\u00e9gl\u00e9e pour donner une pression en aval stable.\r\n\r\n\r\n\r\n\r\n\r\nLorsque la pression en aval augmente, la vanne pilote se ferme et la pression est \u00e9vacu\u00e9e du diaphragme de la vanne principale par l'orifice de commande, pour fermer la vanne principale. Toute variation de charge ou de pression sera imm\u00e9diatement d\u00e9tect\u00e9e sur le diaphragme pilote, qui agira pour ajuster la position de la vanne principale, assurant une pression constante en aval.\r\n\r\n\r\n\r\n\r\n

Comment fonctionnent les r\u00e9gulateurs \u00e0 commande directe\u00a0?<\/h2>\r\n\r\n\r\n\r\n\r\nAu d\u00e9marrage, la pression en amont, aid\u00e9e par un ressort de rappel, maintient la t\u00eate de vanne contre le si\u00e8ge en position ferm\u00e9e.\r\n\r\n\r\n\r\n\r\n\r\nLa pression en aval est r\u00e9gl\u00e9e en tournant le volant dans le sens des aiguilles d'une montre, ce qui comprime le ressort de commande et \u00e9tend le soufflet. Ce mouvement vers le bas est transmis via une tige de pouss\u00e9e, qui provoque l'ouverture de la vanne principale.\r\n\r\n\r\n\r\n\r\n\r\nLa vapeur passe ensuite par la vanne ouverte dans la tuyauterie en aval et entoure \u00e9galement le soufflet.\r\n\r\n\r\n\r\n\r\n\r\n\u00c0 mesure que la pression en aval augmente, elle agit \u00e0 travers le soufflet pour contrecarrer la force du ressort et ferme la vanne principale lorsque la pression r\u00e9gl\u00e9e est atteinte. La vanne principale module pour donner une pression constante.\r\n\r\n","link":"https:\/\/zecovalve.com\/fr\/tag\/spirax-sarco-prv","name":"Spirax Sarco PRV","slug":"spirax-sarco-prv","taxonomy":"post_tag","meta":[],"yoast_head":"\nSpirax Sarco PRV - Spirax Sarco Houston | 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\/fr\/tag\/spirax-sarco-prv\" \/>\n<meta property=\"og:locale\" content=\"fr_FR\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Spirax Sarco PRV - Spirax Sarco Houston | ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"What is Spirax Sarco Houston?

Spirax Sarco has strategically located manufacturing plants around the world including one near Houston in Pasadena, Texas. What is Spirax Sarco PRV? Well-designed steam systems produce clean, dry steam for delivery at high pressure \u2014 the best-quality steam at the lowest cost. Lower-pressure steam is usually needed at the point of use. Effective control demands an automatic valve that can reduce steam pressure accurately, reliably, and at a cost to suit the application. Like direct-acting pressure-reducing valves, these valves are self-powered. The pilot operation provides accurate control under large load-change conditions. Available in iron, cast steel, and stainless steel in sizes from 1\/2\u2033 to 8\u2033. GET SPIRAX SARCO PRV PRICE How does the 25P Pilot Regulator Works? The Spirax Sarco pilot-operated pressure regulator works by balancing the downstream pressure against a control spring. This modulates a small valve head over a seat (the pilot). The flow through this seat is directed, in turn, to the main valve diaphragm, where it modulates the main valve. In order to achieve the most stable operating condition, an external pressure sensing line must be used. This allows downstream pressure to feedback to the underside of the pilot diaphragm, balancing the spring force, and causing the pilot valve to throttle. This settles the pilot valve, allowing a constant flow across the main diaphragm. This ensures that the main valve is also settled to give a stable downstream pressure. When downstream pressure rises, the pilot valve closes, and pressure is released from the main valve diaphragm through the control orifice, to close the main valve. Any variations in load or pressure will immediately be sensed on the pilot diaphragm, which will act to adjust the position of the main valve, ensuring a constant downstream pressure. How do Direct Operated Regulators work? On start-up, upstream pressure, aided by a return spring, holds the valve head against the seat in the closed position. Downstream pressure is set by rotating the hand wheel in a clockwise direction which compresses the control spring and extends the bellows. This downward movement is transmitted via a push rod, which causes the main valve to open. The steam then passes through the open valve into the downstream pipework and also surrounds the bellows. As downstream pressure increases, it acts through the bellows to counteract the spring force and closes the main valve when the set pressure is reached. The main valve modulates to give constant pressure.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/zecovalve.com\/fr\/tag\/spirax-sarco-prv\" \/>\n<meta property=\"og:site_name\" content=\"ZECO Valve\" \/>\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\":\"fr-FR\"},{\"@type\":\"CollectionPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/spirax-sarco-prv#webpage\",\"url\":\"https:\/\/zecovalve.com\/tag\/spirax-sarco-prv\",\"name\":\"Spirax Sarco PRV - Spirax Sarco Houston | ZECO Valve\",\"isPartOf\":{\"@id\":\"https:\/\/zecovalve.com\/#website\"},\"breadcrumb\":{\"@id\":\"https:\/\/zecovalve.com\/tag\/spirax-sarco-prv#breadcrumb\"},\"inLanguage\":\"fr-FR\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/zecovalve.com\/tag\/spirax-sarco-prv\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/zecovalve.com\/tag\/spirax-sarco-prv#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\/spirax-sarco-prv\",\"url\":\"https:\/\/zecovalve.com\/tag\/spirax-sarco-prv\",\"name\":\"Spirax Sarco PRV\"}}]}]}<\/script>\n<!-- \/ Yoast SEO Premium plugin. -->","_links":{"self":[{"href":"https:\/\/zecovalve.com\/fr\/wp-json\/wp\/v2\/tags\/2373","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zecovalve.com\/fr\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/zecovalve.com\/fr\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/zecovalve.com\/fr\/wp-json\/wp\/v2\/posts?tags=2373"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
