At $11.86, it is the smallest and most affordable valve in the Castair BV series, sized for 1\/4\" NPT lines used in pilot connections, drain valve outlets, instrumentation taps, and small auxiliary air lines on Castair compressor installations.\u003c\/p\u003e\n\u003ch2\u003eWhere 1\/4\" Valves Are Used\u003c\/h2\u003e\n\u003cp\u003eA 1\/4\" NPT shutoff valve shows up in several places on a reciprocating compressor system. Pilot valve connections are typically 1\/4\" NPT. Pressure gauge taps, condensate drain lines, and auxiliary ports on aftercoolers and filters often use 1\/4\" NPT connections. The BV25 gives you a positive, positive-shutoff valve at any of these points — a 90-degree turn of the handle takes the line from full flow to fully isolated.\u003c\/p\u003e\n\u003cp\u003eThe full-flow design means the bore through the ball matches the 1\/4\" pipe ID. At this pipe size, the difference between full-flow and reduced-bore is less significant than at larger sizes, but the full-flow valve still offers better flow characteristics and easier maintenance access when the valve body needs to be serviced.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e BV25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size:\u003c\/strong\u003e 1\/4\" NPT Female (both ends)\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\u003ePrice:\u003c\/strong\u003e $11.86\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Cast Air (Castair)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Accessories\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1\/4\" NPT Female Connections:\u003c\/strong\u003e Fits standard 1\/4\" NPT pilot, drain, gauge, and auxiliary ports on compressed air equipment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Flow Design:\u003c\/strong\u003e Full-port ball bore — matches pipe ID for minimum flow restriction\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePositive Shutoff:\u003c\/strong\u003e Quarter-turn handle — fully open or fully closed with no in-between leakage positions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Size:\u003c\/strong\u003e Small enough to fit in tight plumbing locations common on compressor manifolds and aftercooler connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePilot valve isolation on Castair compressor unloader systems (1\/4\" NPT pilot ports)\u003c\/li\u003e\n\u003cli\u003eCondensate drain valve on aftercoolers and moisture separators\u003c\/li\u003e\n\u003cli\u003ePressure gauge isolation valves — shut off the gauge for replacement without taking the system down\u003c\/li\u003e\n\u003cli\u003eAuxiliary air line shutoff for 1\/4\" NPT supply connections to instrumentation or low-demand tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eBV Series Complete Range\u003c\/h2\u003e\n\u003cp\u003eCastair BV full-flow ball valves cover 1\/4\" through 1-1\/2\" NPT: BV25 (1\/4\", $11.86), BV100 (1\", $40.66), BV125 (1-1\/4\", $57.60), BV150 (1-1\/2\", $81.31).
