It features a 1\/4\" MNPT container connection and a 275 PSIG start‑to‑discharge setting, providing a defined relief point to safeguard downstream components. The brass body and seat disc assembly are built for durability, with an operating temperature range of -40°F to 165°F, suitable for outdoor or harsh environments. Typically installed between shut‑off valves or on the side boss of RegO shut‑off valves, it offers a controlled discharge path when pressure exceeds the set point. Common applications include propane\/butane distribution, LPG bulk storage, and related ammonia gas service where external relief protection is required.\u003c\/p\u003e\u003c\/div\u003e","brand":"Rego","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46285476757738,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-024.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/rego-b-9422nh-pressure-relief-valve","provider":"GTG Hardware","version":"1.0","type":"link"}
