Gardner Denver pneumatic relief valve screw air compressor accessories

Model: Gardner Denver pneumatic relief valve 90AR1082 TD

The Gardner Denver Air Control Purge Valve (Part Number: 90AR1082) is a high-precision pneumatic control component engineered for industrial rotary screw air compressors.In the Gardner Denver, FS Curtis, and FuSheng multi-brand shared engineering ecosystems, this valve serves a critical dual function. It acts as a 2-way, diaphragm-pilot operated control valve that governs the air/oil purge cycle and automates system condensate blow-down routines.  

By managing the pressure-release and moisture-discharge intervals, the valve prevents dangerous liquid water buildup inside the primary air lines.This protects downstream pneumatic tools and controls from corrosion, system rust, and costly mechanical drag.
