Hydrant Pit Valve CLA-VAL 352GF
The Cla-Val Model 352GF Hydrant Pit Valve is a piston style, pilot operated on / off valve designed for use in aircraft refueling hydrant systems.
The Model 352GF Hydrant Pit Valve can be ordered with either a manual deadman pilot or a pneumatic deadman pilot. When fitted with a pneumatic pilot, an optional emergency air release lanyard for manual override can be added to provide a way to close the pit valve even with deadman air pressure actively applied.
The outlet of the Model 352GF Hydrant Pit Valve can be connected to by any 4 inch API hydrant pit coupler, such as the Cla-Val Model 351GF-15 Hydrant Coupler and 353GF Pressure Control Coupler.
It complies with the requirements of EI Specification 1584 Fourth Edition.
The upper API body of the Model 352GF Hydrant Pit Valve is made of hardened stainless steel. The lower body is made of ductile iron. Aluminium is not used for these critical pressure containing components.
It incorporates a servicing valve which allows for the removal of the pilot for service without the need to de-pressurize the delivery system.
