Rated at 30 psi, this valve opens automatically when system pressure exceeds the set point, venting excess pressure to prevent equipment damage or failure. The 3\/4 inch male inlet connection makes it compatible with standard boiler configurations. Built from bronze for corrosion resistance in hydronic heating applications, this valve is a direct safety component installed by licensed plumbers and hydronic heating technicians.\u003c\/p\u003e\n\u003cp\u003eThis pressure relief valve is used in residential and light commercial hot water boiler systems. It is typically installed at or near the boiler vessel at the designated relief valve port. The 30 psi pressure rating suits low-pressure hydronic heating systems where boiler operating pressure stays well below the valve set point. Plumbers and heating technicians install this valve during new boiler installations, boiler replacements, or as a scheduled safety device replacement when an existing valve shows signs of weeping, corrosion, or age-related degradation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e30 psi pressure relief rating for low-pressure hydronic boiler systems\u003c\/li\u003e\n  \u003cli\u003eBronze construction for corrosion resistance in hot water applications\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch male inlet connection for standard boiler port fitment\u003c\/li\u003e\n  \u003cli\u003eAutomatic pressure-actuated operation with no external power required\u003c\/li\u003e\n  \u003cli\u003eSold individually (unit of measure: each)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement pressure relief valve for residential and light commercial hot water boiler systems with a 3\/4 inch male inlet port and a maximum allowable working pressure at or above 30 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or hydronic heating technician in accordance with local plumbing codes and ASME boiler and pressure vessel standards. Shut down and depressurize the boiler system completely before removing the existing relief valve. Do not plug, cap, or restrict the discharge port of the installed valve. Verify the valve pressure rating matches the boiler nameplate maximum allowable working pressure before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 30 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: 3\/4 inch male\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrdering Code\u003c\/strong\u003e: 0342692\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WATTS BRASS TUBULAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3\/4 M335M2-030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51525486051634,"sku":"3\/4 M335M2-030","price":2154.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4aa80fd03a3d3a09d720fdb87ae93d5.jpg?v=1785475297","url":"https:\/\/voomisupply.com\/products\/watts-brass-tubular-3-4-m335m2-030-boiler-relief-valve","provider":"Voomi Supply","version":"1.0","type":"link"}
