This valve responds precisely to a set pressure of 6 bar, thus ensuring the safe operation of your heating or hot water system.\u003c\/p\u003e\u003cp\u003eCompliant with the requirements of TRD 702, DIN 4753 Part 1, and DIN 1988, this pressure relief valve serves as an essential safety device. The angled design with integrated lifting device simplifies both installation and maintenance of the valve. The robust housing is made of corrosion-resistant brass, while the spring cap is made of durable plastic. Both the sealing disc and the diaphragm are made of a special, hot-water-resistant elastomer (EPDM), guaranteeing high reliability even at temperatures up to 100°C. The design of the diaphragm safety valve ensures consistent sealing, even under sustained loads and changing operating conditions.\u003c\/p\u003e\u003cp\u003eThanks to IG-IG connections, the safety valve 1\/2\" x3\/4\" for easy integration into existing piping systems. It is ideally suited for water as the operating medium and meets all common safety requirements for modern heating and hot water systems.\u003c\/p\u003e\u003ch3\u003eTechnical data:\u003c\/h3\u003e\u003cul\u003e  \u003cli\u003eInlet connection\/Outlet connection: 1\/2” x 3\/4”\u003c\/li\u003e  \u003cli\u003eSet pressure: 6 bar\u003c\/li\u003e  \u003cli\u003eSealing gasket: EPDM (hot water resistant elastomer)\u003c\/li\u003e  \u003cli\u003eMaximum permissible operating temperature: 100°C\u003c\/li\u003e  \u003cli\u003eTemperature range: 5 ÷ 100°C\u003c\/li\u003e  \u003cli\u003eOperating fluid: water\u003c\/li\u003e  \u003cli\u003eIG-IG connections for easy installation\u003c\/li\u003e  \u003c\/ul\u003e\u003cp\u003e*Technical changes reserved | Images may vary\u003c\/p\u003e","brand":"Caleffi","offers":[{"title":"Default Title","offer_id":47030976217436,"sku":"ARTMSV126","price":9.64,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/7796\/6428\/files\/caleffi-membran-sicherheitsventil-12-x-34-6-bar-heizungsventil-2601865.webp?v=1770693498","url":"https:\/\/lu.gemashop.de\/en\/products\/membrane-safety-valve-1-2-x-3-4","provider":"GEMA Shop","version":"1.0","type":"link"}
