Built to ASTM B61 material grade and conforming to MSS SP-80, this valve is designed for inline installation in piping systems where backflow prevention is required. It opens at a crack pressure of 0.50 psi and handles operating pressures from 5 psi up to full WOG rating. The all-bronze body and bronze seal construction make it suitable for service in gas, oil, and water systems. Licensed plumbers and pipefitters are the primary installers for this type of valve in both commercial and industrial piping applications.\u003c\/p\u003e\n\u003cp\u003eThis check valve is suited for use in residential and light commercial plumbing, hydronic heating, fuel oil, and gas distribution piping where a reliable, low-cracking-pressure non-return device is needed. Its 1-1\/4 inch NPT threaded connections allow direct makeup into standard threaded pipe assemblies. The valve is rated for service from -20 degrees F to 550 degrees F, covering a wide range of fluid temperatures encountered in typical mechanical room and inline piping applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e400 WOG pressure rating suitable for water, oil, and gas service\u003c\/li\u003e\n  \u003cli\u003eAll-bronze body and seal construction per ASTM B61 material grade\u003c\/li\u003e\n  \u003cli\u003eLow crack pressure of 0.50 psi allows operation in low-differential systems\u003c\/li\u003e\n  \u003cli\u003eThreaded NPT end connections for straightforward installation into existing pipe runs\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -20 degrees F to 550 degrees F\u003c\/li\u003e\n  \u003cli\u003eConforms to MSS SP-80 standards for bronze gate, globe, angle, and check valves\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation check valve for 1-1\/4 inch NPT threaded piping systems handling gas, oil, or water service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC requirements where gas service is involved. Shut off and depressurize the piping system completely before removing or installing the valve. Apply thread sealant or PTFE tape rated for the service medium to all NPT connections before makeup. Verify flow direction arrow on the valve body before final installation to ensure correct orientation for backflow prevention.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Check\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: NPT (Threaded)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 400 WOG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrack Pressure\u003c\/strong\u003e: 0.50 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Pressure\u003c\/strong\u003e: 5 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 550 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -20 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Bronze (ASTM B61)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Gas, Oil, Water\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: MSS SP-80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.16 pounds\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: MILWAUKEE VALVE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 508-114\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE VALVE","offers":[{"title":"Default Title","offer_id":51698084577586,"sku":"508-114","price":174.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/832aac30ed7aa572ec9e603f9ca10030.jpg?v=1788357509","url":"https:\/\/voomisupply.com\/products\/milwaukee-valve-508-114-bronze-check-valve-1-1-4-in-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
