It consists of an iron body construction with expanded outlet drain connections for hot water space heating boilers, non-metallic disc-to-metal seating, stainless steel spring, and test lever. It offers large discharge capacity, resists corrosive water conditions, resists 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 pressure relief is set at 50 psi ( 344.7 kPa) with corresponding high pressure ratings up to 1,352,000 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\u003eSpring loaded\u003c\/li\u003e\n\u003cli\u003eSet at 50 psi\u003c\/li\u003e\n\u003cli\u003eIron body construction\u003c\/li\u003e\n\u003cli\u003eAutomatic reseating\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\u003eIron\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\u003eNO\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEAN\u003c\/td\u003e\n\u003ctd\u003e098268018899\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\u003eNot In Scope\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\u003e38\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutlet Connection Size\u003c\/td\u003e\n\u003ctd\u003e1 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\u003e0382328\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Range\u003c\/td\u003e\n\u003ctd\u003e30 to 75 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Relief Setting-PSI\u003c\/td\u003e\n\u003ctd\u003e50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Steam Discharge Capacity\u003c\/td\u003e\n\u003ctd\u003e1,352,000 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\u003e740\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 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":47344122331309,"sku":"0382328","price":137.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/5895\/3645\/files\/740.tif.2.jpg?v=1787903147","url":"https:\/\/www.bostonheatingsupply.com\/products\/watts-0382328-740-050-3-4-iron-boiler-pressure-relief-valve","provider":"Boston Heating Supply","version":"1.0","type":"link"}
