They automatically maintain the desired maximum pressure within a vessel or system by discharging excess pressure into a lower-pressure return line or to the atmosphere. These valves are ideal for pump bypass control, ensuring consistent pump discharge pressure. They can function as continuously operating valves or provide intermittent protection against overpressure conditions.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eAlso Known As:\u003cbr\u003e\u003cbr\u003e\u003c\/strong\u003eDirect-acting pressure regulator, direct-acting pressure-reducing valve, spring-loaded pressure regulator, direct spring-operated regulator, mechanical pressure regulator.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003cbr\u003e\u003cbr\u003e\u003c\/strong\u003e\u003cspan\u003e• Fast response\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e• Viton Trim for 300°F service\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e• Soft “Seat” for tight shut-off\u003c\/span\u003e\u003c\/p\u003e\n\u003c!----\u003e","brand":"Watson McDaniel","offers":[{"title":"Default Title","offer_id":55236246798705,"sku":"R-12-N-4","price":230.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0213\/7895\/7412\/files\/Driver_50_bb85c302-bc90-4f0a-a10a-e7d10c16d668.jpg?v=1763025188","url":"https:\/\/nassaunationalcable.com\/products\/1-2-inch-direct-operated-relief-back-pressure-regulating-valve-r-12-n-4","provider":"NassauNationalCable","version":"1.0","type":"link"}
