Model 60554E
Air-operated pilot valve for deadman control. Valve allows flow in the fueling direction only.
Model 60554F
Dual air and lanyard operated pilot valve for deadman control and manual on/off control for use in small pits only (12 or 13-inch dia.). Uni-directional only, unless combined with Option J.
Model 60554J
Air-operated pilot valve for deadman control with defuel control to allow flow of fuel in either fueling or defueling direction
