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.
The Model 353GF Pressure Control Coupler has been designed and tested to
comply with all requirements of EI 1584 “Four Inch Hydrant System Components
and Arrangements”, Second Edition. The Coupler makes a very robust connection to
any 4 inch API style hydrant pit valve or hydrant adapter. This connection greatly
exceeds the side-pull requirements of the EI Bulletin 1584. Yet, because of the use
of hardened Stainless Steel balls to make this connection, the Coupler can easily turn
when connected to remove stress on the intake hose connected to the outlet of the
Coupler. The Model 353GF Pressure Control Coupler incorporates a pressure regulating valve that is deadman operated. The Coupler can be configured to accept either compressed air (Option A) or pressurized fuel (Option H) as the motive deadman fluid.
