Industrial PILOT-UNLOADER-VALVE-1/2-1/2-30CFM Check Valve

This Pilot Unloader Check Valve for Gas-Powered Air Compressors (1/2" × 1/2", 30 CFM) regulates tank pressure and automatically unloads during startup and shutdown. It combines a check valve and unloading function in a brass-body valve with a 1/2 in NPT inlet and 1/2 in NPT outlet for inline threaded connections, typically operating up to 175 PSI. The one-way flow and automatic unloading help reduce engine starting load and prevent backflow in gas-powered reciprocating air compressors, pressure tanks, and pump assemblies. As a standard industrial replacement component, it serves automotive, construction, manufacturing, and general industrial applications where reliable pressure regulation is critical. Compatible equipment includes reciprocating air compressors and pressure tanks, with common retrofits aligning to Conrader STV Series, Conrader HCV Series, or Campbell Hausfeld CW209300AV. The brass construction provides corrosion resistance, and its function supports both pressure relief and backflow prevention to promote safer startup and operation.
