It consists of a bronze body construction with NPT threaded female inlet and NPT threaded female outlet (drain) connections, non-metallic disc-to-metal seating, stainless steel spring, and test lever. It resists corrosive water conditions, sticking and freezing, and prevents water and sediment from being trapped in the seat. It is designed for emergency safety relief, not as an operating control. The standard pressure setting is 30psi (206.9 kPa), Pressure Range: In 5psi (34.5 kPa) increments from 30 to 150psi (2 to 10 bar) with corresponding high ratings from 650,000 to 14,370,000 BTU\/hr.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"product__additional-details\"\u003e\n\u003cp class=\"js-jump-links-target\"\u003e\u003cb\u003eFeatures\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eStandard pressure relief setting 30 psi\u003c\/li\u003e\n\u003cli\u003eBronze body\u003c\/li\u003e\n\u003cli\u003eBronze Body Construction\u003c\/li\u003e\n\u003cli\u003eFor hot water heating and supply boilers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003ctable class=\"product__specifications\" style=\"width: 375px;\" border=\"1\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003cth colspan=\"2\"\u003eSpecifications\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003eBronze\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\u003e098268013054\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGDS Status\u003c\/td\u003e\n\u003ctd\u003eRegistered\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGPM-When Relieved\u003c\/td\u003e\n\u003ctd\u003eDoes Not Apply to Product\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\u003eFemale 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 Temperature-Fahrenheit\u003c\/td\u003e\n\u003ctd\u003e250\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Working Pressure-PSI\u003c\/td\u003e\n\u003ctd\u003e20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutlet Connection Size\u003c\/td\u003e\n\u003ctd\u003e3\/4 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\u003e0274428\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Range\u003c\/td\u003e\n\u003ctd\u003e30 to 150 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Relief Setting-PSI\u003c\/td\u003e\n\u003ctd\u003e30\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Steam Discharge Capacity\u003c\/td\u003e\n\u003ctd\u003e650,000 BTU per hour\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Type\u003c\/td\u003e\n\u003ctd\u003ePressure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003e174A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShank Length\u003c\/td\u003e\n\u003ctd\u003eDoes Not Apply to Product\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Relief-Fahrenheit\u003c\/td\u003e\n\u003ctd\u003e9999\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Steam Discharge Capacity\u003c\/td\u003e\n\u003ctd\u003eDoes Not Apply to Product\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThermostat Material\u003c\/td\u003e\n\u003ctd\u003eDoes Not Apply To Product\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThermostat Probe Length\u003c\/td\u003e\n\u003ctd\u003eDoes Not Apply to Product\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Watts","offers":[{"title":"Default Title","offer_id":47344109650093,"sku":"0274428","price":212.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/5895\/3645\/files\/174A.16.jpg?v=1787902877","url":"https:\/\/www.bostonheatingsupply.com\/products\/watts-0274428-174a-030-3-4-bronze-boiler-pressure-relief-valve","provider":"Boston Heating Supply","version":"1.0","type":"link"}
