Cla-Val - Model 353GF -Pressure Control Coupler

The Model 353GF Pressure Control Coupler is a hydrant coupler used in jet aircraft refueling operations. It connects to a hydrant pit valve or hydrant pit adapter to allow pressurized fuel to flow from an underground pipeline and into the receiving aircraft. It incorporates a Deadman operated, direct-acting pressure regulator that protects the receiving aircraft from excess pressure and from damage due to pressure surges.
