Description: An Air Operated Valve is a type of power operated valve that uses air pressure against a piston or diaphragm to produce linear or circular movement to operate a valve. These valves are used for application up to 60,000 PSI and up to 100,000 PSI output; and the input air requirement from 15 to 80 PSI. We provide normally open and normally closed valves which can be controlled by air regulator, electrical solenoid or low pressure valves. We also offer remote metering valves.
