With a 1\/4 inch MNPT inlet connection and a maximum working pressure of 125 psi, this valve automatically vents excess pressure to prevent equipment damage or failure. The brass body provides corrosion resistance suitable for air compressor and pneumatic system applications. A fluorocarbon seal handles a working temperature range of -15 degrees F to 250 degrees F, making it reliable across a wide range of service conditions. Licensed plumbers, pipefitters, and HVAC technicians install this valve as a primary pressure-relief safety device.\u003c\/p\u003e\n\u003cp\u003eThe ST25-1A125 is suited for residential and light commercial compressed air systems, pneumatic equipment, and pressure vessels where a compact 1\/4 inch NPT connection is required. Its 116 CFM flow capacity handles the relief demands of small to mid-size air compressors and similar pressurized equipment. This valve is intended for installations where ASME safety standards are required by code, including equipment rooms, utility spaces, and mechanical areas serviced by licensed tradespeople.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASME-rated safety relief valve for code-compliant pressure protection\u003c\/li\u003e\n  \u003cli\u003e125 psi maximum working pressure with 116 CFM relief capacity\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch MNPT inlet for straightforward threaded installation\u003c\/li\u003e\n  \u003cli\u003eBrass body construction for corrosion resistance in air and pneumatic service\u003c\/li\u003e\n  \u003cli\u003eFluorocarbon seal rated from -15 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eCompact form factor for installations with limited clearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ASME-compliant replacement safety relief valve for pressurized systems and equipment requiring a 1\/4 inch NPT connection rated to 125 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or HVAC technician in accordance with applicable mechanical codes and ASME standards. Always depressurize and isolate the system completely before removing an existing relief valve or installing a new one. Apply thread sealant appropriate for the service media to the MNPT threads, and do not over-tighten, as brass fittings can be damaged by excessive torque. Verify the valve set pressure matches the equipment nameplate rating before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: ASME Safety Relief\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 125 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Capacity\u003c\/strong\u003e: 116 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -15 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Fluorocarbon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141606\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: CONTROL DEVICES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ST25-1A125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CONTROL DEVICES","offers":[{"title":"Default Title","offer_id":51538259542322,"sku":"ST25-1A125","price":18.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fab829ad8dd125f50b5b55f26d487ba3.jpg?v=1785821113","url":"https:\/\/voomisupply.com\/products\/control-devices-st25-1a125-safety-relief-valve-125-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
