The safety valve is an indispensable safety equipment of air compressor.

Brass construction and stainless steel spring for corrosion resistance.

The valve openings allow fluids or gases to escape to decrease pressure, and then close once the valve reaches the reseating pressure limit.

They also relieve excess vacuum by opening to release a gas into the system and then closing after it reaches its low-pressure limit.

Relief valves are used in a variety of applications, such as air compressors, petrochemical and chemical manufacturing, natural gas processing, and power generation.

1/4" NPT 325 PSI Air Compressor Brass Safety Relief Pressure Valve Tank Pop Off

1/4" male NPT 325 PSI Industrial air compressor/tank pressure safety relief valve. Also known as a "Pop Off" or "Blow Off" valve.
