Collection: Accessories - Pilot Valves

Pilot valves for Cast Air reciprocating compressors — OEM replacement unloader control valves built to the same cast iron standards as the compressors themselves. Cast Air has manufactured compressor components in Spicer, MN since 1991, and these pilot valves are engineered to match original factory specifications for proper unloader operation and pressure cycling.

Each pilot valve is designed for direct replacement on Cast Air reciprocating models, maintaining correct cut-in and cut-out pressure differentials without modification. Cast iron construction throughout means consistent performance under the thermal and pressure cycling conditions of daily compressor use.

As an authorized Cast Air dealer, we stock pilot valves for current and legacy Cast Air compressor models. If you need help confirming the correct part for your unit, call us at 866-217-0063.
