Threaded Safety Valves

Compressor Safety Valves

A compressor safety valve is a small spring-loaded safety valve that opens when pressure in an air compressor receiver exceeds the set value, relieving excess air.

It is used on piston and screw compressor receivers, air lines and compressed air equipment. The product range includes models with 1/4″ and 1/2″ connections.
