Air-operated valve

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.Air Valves perform two important functions in a piping system. They maintain system design efficiency and provide system protection. System efficiency is maintained by venting air via the air valves from the system that can restrict flow and increase pumping costs.

Protection is provided by exhausting and admitting air through the air valves during system operations including start-up, shutdown, and critical conditions such as power failures or line breaks. The exhausting and admitting of air during these conditions will reduce the potential for destructive surges and water hammer normally associated with uncontrolled air or a vacuum condition within the piping system.

Types Of Air Operated Valves

• 2 way solenoid valve
• 3 way solenoid valve

2 way solenoid valve

the 2 way solenoid valves can be either normally closed or normally opened These 2-way packless internal pilot operated valves are available in a wide range of sizes and are available with either sil brazed union ends Many are supplied with manual operating devices and meet the Hi-Shock requirements

3 way solenoid valve

These 3-way normally closed, normally open and universal operation, direct acting, fully automatic solenoid operated valves are a modification of our standard Bulletin 8320 & 8300 valves. These packless valves require no minimum operating pressure and are furnished with soft seats for bubble tight shut-off. A screw type manual operator is also furnished. These valves meet the Hi-Shock requirements of MIL-S-901 and vibration requirements of MIL-STD-167.
