Stainless steel cryogenic emergency shut off gate valve with bolted bonnet and integral pneumatic actuator. Fail safe and automatic operation. The valve is held open by pneumatic air pressure and closes automatically on air vent or the loss of the pneumatic air supply pressure, for whatever reason.
The bellows type pneumatic actuator includes a single convoluted air spring actuator of rubber connections with manual override.
The valve has a wedge seat design for tight shut off to seal on the downstream seat only in order to prevent liquid lock. The bolted bonnet allows for simple site maintenance, with easy access to the serviceable parts of the valve.
All valves are degreased for oxygen duty, assembled in clean room conditions and pressure tested prior to despatch.
