Direct Pilot Operated
Lexair direct pilot operated valves can be used with a variety of media where quick, positive control and long service life are required from an extremely low pilot signal. Featuring a standard operating pressure of 500 PSI, these durable, high flow units are perfect for any of your high pressure application requirements. With optional seals, they require no lubrication, making them ideal for non-lube air service.
Our valves feature a large resilient poppet that provides bubble-tight closure, even under low pressure conditions. Internal components made from bronze, brass and stainless steel plus a wide choice of seal materials assure excellent compatibility with a broad range of media. These valves are available with a variety of pilot-to-line-pressure ratios.
The bottom hex nut is easily removed for quick access to the valve’s poppet assembly. A PolyPak™ seal on the stem and a U-cup pilot piston seal prevent controlled and pilot media from mixing, permitting use of different media for pilot/control.
Valve sizes from 1/4” to 3/4” utilize a threaded pilot cap; valve models in larger sizes (as well as valve models with 8:1 line pressure versus pilot pressure) use bolt-on pilot caps. Click here for an inside view with additional information/ features.
