102GA, 102GH

Pilot operated check valves

Technical features

Medium	Compressed air
Operation	Essentially a pilot operated check valve, a blocking fitting allows air flow in both directions if a pilot pressure is applied to port 12. When pressure to the pilot port is removed, flow occurs in one direction only, due to an integral non-return valve. When used in pairs, blocking fittings can control an actuator to give safe operation in the event of an electrical problem, air failure or tube breakage. In order to provide a ‘safe system’, all possible conditions need to be considered in the event of an emergency.
