As the 14550 directional control valve, but with an actuator so that it can be operated remotely through a pneumatic signal (but with the handle providing an override option). In the closed position, the plunger makes a leak-free seal with the seat. Being dynamically biased towards closing, the seal becomes tighter as pressure rises.

A module can be readily withdrawn from the base of the valve body for servicing or renewing the seat or seals. Total handle movement of 90° gives positive detented selections at 45° intervals.

The valve is suitable for use with a wide range of fluids and is designed for working pressures of up to 10,000 psi.

Torque required to operate the handle remains light throughout the pressure range and can readily be provided by the actuator.

Under actuator control, the directional control valve is switched between handle position 1 and handle position 2. The centre position is only obtained manually.
