ABSTRACT:
A housing has a cage with supply fluid ports, vent ports and an outlet port. A pilot actuated hollow spool valve element is telescopically movable in the cage and engages poppet seats at opposite ends of the cage. Elongated supply and vent slots directed transversely to the axis of the cage and valve element provide maximum flow passages. The ends of the spool are in contact with the cage at all times and the axial extent of the contact between the spool and the cage is greater than fifty percent. The spool engages the interior of the cage at the fluid ports and vent ports for reducing flow restrictions. A recess coaxially positioned at each end of the cage receives one of the valve seats. The housing abuts the cage for properly loading the valve seats. A dash pot cushions the valve element. A pilot control stem is connected to the valve element exteriorly of the valve element. A seal carrier provides a seal between mating surfaces of an underwater control pod.
