Armstrong GD-22 Pressure Reducing Relief Valve

Armstrong GD-22 Pressure Reducing Relief Valve is a compact, self-contained valve designed to regulate downstream pressure and provide relief protection in overpressure scenarios. It features 5/8" ports and 3/4" flange connections arranged in a four-bolt pattern, enabling straightforward installation in tight process lines. As part of Armstrong's GD-series, the GD-22 is built for simple, maintenance-friendly pressure control in industrial piping where a small footprint and uncomplicated installation are advantageous. The 5/8" ports, 3/4" flange sizing, and four-bolt arrangement support connections to small-diameter piping and compact assemblies. Downstream pressure is typically user-defined via the valve setpoint, allowing operators to tailor the regulator to process requirements while maintaining system protection against overpressure. This combination of compact porting, flange sizing, and a four-bolt pattern makes the GD-22 a practical choice for spaces-constrained installations or retrofits that require reliable, localized pressure control without complex pilot systems.
