It consists of a bronze body construction with 3\/4 inch NPT threaded male inlet and 1\/2 inch NPT threaded female (drain) outlet connections, stainless steel spring, brass bonnet, Buna-N disc, and Buna-N O-ring. It has a calibrated adjustment feature for setting the valve to the required relief pressure, and is ideal for by-pass thermal expansion pressure relief (not ASME approved). It is for use in fire protection systems. The maximum pressure is 300 psi (20.67 bar). The adjustable pressure range is 100 to 300 psi (3.45 to 12.06 bar).\u003c\/p\u003e\n\n\u003cstrong\u003eFeatures\u003c\/strong\u003e\n\u003cul\u003e\n                        \u003cli\u003eBronze body construction\u003c\/li\u003e\n                        \u003cli\u003eAll stainless steel spring\u003c\/li\u003e\n                        \u003cli\u003eDesigned for protection against excessive pressure build up\u003c\/li\u003e\n                        \u003cli\u003emodel also available for fire protection systems\u003c\/li\u003e\n            \u003c\/ul\u003e\n\u003ctable\u003e\n        \u003cthead\u003e\n            \u003ctr\u003e\n                \u003cth colspan=\"2\" style=\"text-align: left;\"\u003eSpecifications\u003c\/th\u003e\n            \u003c\/tr\u003e\n        \u003c\/thead\u003e\n            \u003ctbody\u003e\n\u003ctr\u003e\n                \u003ctd\u003eBody Material\u003c\/td\u003e\n                \u003ctd\u003eBrass\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n                \u003ctd\u003eBrand\u003c\/td\u003e\n                \u003ctd\u003eWatts\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n                \u003ctd\u003eBuy American Act Compliant\u003c\/td\u003e\n                \u003ctd\u003eYES\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n                \u003ctd\u003eEAN\u003c\/td\u003e\n                \u003ctd\u003e098268582482\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n                \u003ctd\u003eInlet Connection Size\u003c\/td\u003e\n                \u003ctd\u003e3\/4 IN\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n                \u003ctd\u003eInlet Connection Type\u003c\/td\u003e\n                \u003ctd\u003eMale Threaded\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n                \u003ctd\u003eInlet Thread Type\u003c\/td\u003e\n                \u003ctd\u003eNPT\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n                \u003ctd\u003eLead Free\u003c\/td\u003e\n                \u003ctd\u003eNO\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n                \u003ctd\u003eMaximum Working Pressure-PSI\u003c\/td\u003e\n                \u003ctd\u003e300\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n                \u003ctd\u003eOutlet Connection Size\u003c\/td\u003e\n                \u003ctd\u003e1\/2 IN\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n                \u003ctd\u003eOutlet Connection Type\u003c\/td\u003e\n                \u003ctd\u003eFemale Threaded\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n                \u003ctd\u003eOutlet Thread Type\u003c\/td\u003e\n                \u003ctd\u003eNPT\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n                \u003ctd\u003ePart Number\u003c\/td\u003e\n                \u003ctd\u003e\u003cspan class=\"highlight\"\u003e\u003cspan class=\"highlight\"\u003e0372273\u003c\/span\u003e\u003c\/span\u003e\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n                \u003ctd\u003ePressure Range\u003c\/td\u003e\n                \u003ctd\u003e50 to 175 PSI\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n                \u003ctd\u003eSeries\u003c\/td\u003e\n                \u003ctd\u003e530C\u003c\/td\u003e\n            \u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/media.mainlinematerials.com\/files\/es-530c-2448.pdf\" target=\"_blank\"\u003eSpecification Sheet - 530C\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\n\u003cb\u003eUPC\u003c\/b\u003e - 098268582482","brand":"Watts","offers":[{"title":"Default Title","offer_id":44887681695944,"sku":"0372273","price":221.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0172\/0762\/3734\/files\/639004235170000000_00e5dde4-c310-496b-8520-9ee659f05e2d.jpg?v=1767122194","url":"https:\/\/www.mainlinematerials.com\/products\/watts-530c-100-300-part-of-the-530c-series","provider":"Mainline Materials","version":"1.0","type":"link"}
