The bronze body and bonnet conform to ASTM B62 (UNS C83600), providing reliable corrosion resistance in water, steam, and general industrial fluid applications. The rising stem design gives a clear visual indication of valve position — open or closed — which is important in commercial plumbing and mechanical room installations. A malleable iron handwheel operates the valve, and a full-port bore minimizes flow restriction. Flow coefficient (Cv) is rated at 90, supporting high-flow system designs. This valve is installed by licensed plumbers and pipefitters.\u003c\/p\u003e\u003cp\u003eThe CRANE 125431gv is suited for residential and commercial plumbing systems, hydronic heating distribution lines, industrial fluid lines, and general utility shutoff applications where a reliable, manually operated isolation valve is required. The 1-1\/4 inch FNPT connections make it compatible with standard threaded pipe systems conforming to ANSI B1.20.1. It is appropriate for use in mechanical rooms, boiler rooms, and process piping where periodic full shutoff is needed. This valve is not rated for use on gas lines or in applications requiring a lead-free compliant valve.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRising stem design provides clear visual open\/closed indication\u003c\/li\u003e\n\u003cli\u003eFull-port bore with Cv of 90 for minimal pressure drop\u003c\/li\u003e\n\u003cli\u003eBronze body, bonnet, stem, and wedge disc (ASTM B62, ASTM B505)\u003c\/li\u003e\n\u003cli\u003e300 PSI CWP non-shock pressure rating at Class 150\u003c\/li\u003e\n\u003cli\u003eFNPT connections conform to ANSI B1.20.1 threading standard\u003c\/li\u003e\n\u003cli\u003eMSS-SP-80 Type 2 compliant construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style Model 431 series Class 150 bronze threaded gate valve for 1-1\/4 inch FNPT threaded pipe systems conforming to ANSI B1.20.1 and MSS-SP-80 Type 2 standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with local plumbing codes and IPC requirements. Depressurize and drain the system fully before removing or installing any valve. Apply thread sealant or PTFE tape to male threads per standard practice; do not overtighten, as bronze fittings can be damaged by excessive torque. Verify that the system operating pressure does not exceed the 300 PSI CWP non-shock rating of this valve.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 300 PSI (CWP) Non-Shock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: Class 150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: FNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Coefficient (Cv)\u003c\/strong\u003e: 90\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Bronze (ASTM B62, UNS C83600)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Material\u003c\/strong\u003e: Bronze (ASTM B505, UNS C83600)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrim Material\u003c\/strong\u003e: Bronze Wedge Disc (UNS C83600)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGland Material\u003c\/strong\u003e: Brass (ASTM BSEN12164, CW614N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Material\u003c\/strong\u003e: Malleable Iron (ASTM A197, UNS F22000)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperator Type\u003c\/strong\u003e: Handwheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Rising Stem, Full-Port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standards\u003c\/strong\u003e: ANSI B1.20.1, MSS-SP-80 Type 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.77 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Center To Top Of Handle\u003c\/strong\u003e: 8.62 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandwheel Diameter\u003c\/strong\u003e: 3.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CRANE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 125431gv\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CRANE","offers":[{"title":"Default Title","offer_id":51268045013298,"sku":"125431GV","price":4611.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/Crane_01288GLV.jpg?v=1780697793","url":"https:\/\/voomisupply.com\/products\/crane-125431gv-gate-valve-1-1-4-in-fnpt-bronze-300-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
