Key operated pneumatic valves used for switching an air supply on or off manually within pneumatic systems can also provide a manual security function that prevents unauthorised machine operation by untrained operatives.
Only by insertion of the key is it possible to operate the valve; the key is removable in one position only, by removing the key the valve is inoperable.
Two keys are provided; they are a standard common key and not unique to each valve. Spare keys are not available to order separately.
Key-operated pneumatic valves are available as a 3 or 5-way valve configuration with G1/8 threaded ports.
We offer an ATEX fully certified, CE marked pneumatic valves that comply with the ATEX directive for use within Group II category 2, zones 1 and 21.
