At $57.60, it is the correctly sized full-flow shutoff valve for the larger discharge lines and higher flow rates of compressors in the 25-40 HP class — where a 1\" valve would be undersized and create a bottleneck in the compressed air supply.\u003c\/p\u003e\n\u003ch2\u003eWhy 1-1\/4\" for 25-40 HP Rotary Compressors\u003c\/h2\u003e\n\u003cp\u003eRotary screw compressors in the 25-40 HP range produce significantly more CFM than a 5-10 HP reciprocating machine. At those flow rates, the discharge line and all downstream components need to be sized to handle that volume without creating pressure drop. A 1-1\/4\" full-flow valve at this discharge point keeps the line fully open with minimal restriction, maintaining the pressure the compressor produces all the way to the distribution system.\u003c\/p\u003e\n\u003cp\u003eUsing a 1\" valve (BV100) on a 40 HP rotary would create a restriction. The BV125 is the correct specification for this compressor class.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e BV125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size:\u003c\/strong\u003e 1-1\/4\" NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type:\u003c\/strong\u003e Full Flow Ball Valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e 25-40 HP Rotary Screw Compressors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrice:\u003c\/strong\u003e $57.60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Cast Air (Castair)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSized for 25-40 HP Rotary Compressors:\u003c\/strong\u003e 1-1\/4\" ID matches the discharge line specifications of rotary screw compressors in this HP range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Flow Design:\u003c\/strong\u003e Full-port ball bore matches pipe ID — no flow restriction when valve is fully open\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePositive Shutoff:\u003c\/strong\u003e Clean open\/close function — holds pressure reliably when closed, no flow when you need the system isolated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard NPT Threads:\u003c\/strong\u003e 1-1\/4\" NPT connects to standard compressor discharge plumbing without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDischarge shutoff valve on 25-40 HP rotary screw compressors\u003c\/li\u003e\n\u003cli\u003eDistribution system isolation valves on high-capacity compressed air systems\u003c\/li\u003e\n\u003cli\u003eShutoff before aftercoolers, dryers, or filters on larger compressor installations\u003c\/li\u003e\n\u003cli\u003eAny 1-1\/4\" NPT compressed air application requiring a full-flow positive shutoff\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eBV Series Selection — Matching Valve to Compressor\u003c\/h2\u003e\n\u003cp\u003eBV25 (1\/4\"): small line, drain valves, pilot connections.
