When system pressure approaches the set pressure, the valve\u2019s full-lift mechanism enables a fast, near-instant opening to maximum lift. This rapid full opening creates a <strong>high-capacity discharge<\/strong> path, allowing excess pressure to be released quickly to reduce the risk of equipment damage, leakage incidents, and unplanned shutdowns.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Why full-lift matters in real operation<\/strong><\/h4>\n\n\n\n<p>In many industrial systems, pressure can rise faster than operators can respond\u2014especially during upset conditions such as blocked outlets, control valve failures, thermal expansion, or rapid phase changes. A full-lift design is preferred when the process requires:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Fast response<\/strong> to overpressure<\/li>\n\n\n\n<li><strong>High relieving capacity<\/strong> to stabilise system pressure quickly<\/li>\n\n\n\n<li>Predictable opening behaviour with repeatable performance<\/li>\n<\/ul>\n\n\n\n<p>This model uses a <strong>closed bonnet design<\/strong>, which helps isolate the spring chamber from environmental influences and the process medium. In practical terms, closed bonnet construction supports more stable performance where external contamination, moisture, or corrosive atmospheres could otherwise affect internals. It also reduces the likelihood of media-related issues around the bonnet area, improving operational safety and site cleanliness.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Compliance and certification (procurement-ready)<\/strong><\/h4>\n\n\n\n<p>This valve is designed and certified to meet commonly specified European requirements:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>VdT\u00dcV<\/strong><\/li>\n\n\n\n<li><strong>AD2000-A2<\/strong><\/li>\n\n\n\n<li><strong>EN ISO 4126-1<\/strong><\/li>\n<\/ul>\n\n\n\n<p>For many EPC, plant owners, and auditors, these references are not \u201cnice to have\u201d\u2014they are often mandatory for acceptance, documentation packages, and commissioning.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Typical applications and suitable media<\/strong><\/h4>\n\n\n\n<p>This general-purpose <strong>full lift safety valve<\/strong> is suitable for a wide range of services, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Steam systems and boilers (where rapid relieving is essential)<\/li>\n\n\n\n<li>Aggressive gases and vapours<\/li>\n\n\n\n<li>Liquids requiring dependable overpressure protection<\/li>\n<\/ul>\n\n\n\n<p>Common industries and use cases include utilities, chemical processing, general manufacturing, and thermal systems where operating conditions vary and reliability is a priority.<\/p>\n\n\n\n<p><\/p>","protected":false},"featured_media":118,"menu_order":0,"template":"","product-categories":[27,14],"class_list":["post-531","product","type-product","status-publish","has-post-thumbnail","hentry","product-categories-high-flow-safety-valves","product-categories-safety-relief-valves"],"acf":[],"_links":{"self":[{"href":"https:\/\/cartervalves.com\/de\/wp-json\/wp\/v2\/product\/531","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cartervalves.com\/de\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/cartervalves.com\/de\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cartervalves.com\/de\/wp-json\/wp\/v2\/media\/118"}],"wp:attachment":[{"href":"https:\/\/cartervalves.com\/de\/wp-json\/wp\/v2\/media?parent=531"}],"wp:term":[{"taxonomy":"product-categories","embeddable":true,"href":"https:\/\/cartervalves.com\/de\/wp-json\/wp\/v2\/product-categories?post=531"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
