The pilot piston can be sized to vary the pilot actuation pressure between 2 and 80 bar. The external pilot actuator is designed to operate at a pressure of 40 bar, although alternatives can be offered on request. For oil pilot, the actuator is supplied with a dual seal and air vent design to prevent cross contamination of the fluids.

Return Options, The valves shown are all spring return however, the valves can be offered with a detent function and pilot return if preferred.

Functions,

4/3 with blocked P, AB&T joined at the centre
4/3 with open centre All ports joined at centre
4/2
3/2 N/O
3/2 N/C

The size of the pilot actuation can be modified to generate an actuation of different pilot pressure. For specific operating range contact TWHC. The DN16 is also available with an integral 3/2 solenoid operated pilot actuation valve.

Electrical Actuation, Due to actuation forces and stroke length a direct solenoid operation is not possible with this size of valve. However, stepper motor
control is under development.
