Pneumatic key operated valves shown in this section are designed to fit alongside 22mm diameter electrical push-buttons to give a uniformed panel appearance.

Key operated pneumatic valves are bistable; upon release of the key they maintain their position, typically they are used for switching an air supply on or off manually. The key is removable in one position only, by removing the key, pneumatic systems or devices can be made inoperable.

Two keys with each valve are supplied. Keys are universal and not unique. Spare keys are not available to buy separately.

Air pilot assisted versions for a lighter actuation are available - the key switch is auxiliary supported, this reduces the force required to operate the valve resulting in a lighter operation.

Key operated pneumatic valves include a 3 or 5-way valve configuration with G1/8 threaded ports. ATEX approval is optional with many of these valves; details are in the download section of this website. Visit our online shop for stock and pricing information.
