    Solenoid Pilot Valve
    For efficient operation of HP series pneumatic actuators, choose DynaQuip pilot solenoid valves:

    • Pilot solenoid valves electrically control the air supply coming into the actuator.
    • Standard NEMA 4 Housing (additional NEMA ratings available).
    • The solenoid pilot valve pressurizes and exhausts the actuator piston compartments to cause the actuator to move.
    • The 4-way solenoid pilot valve mounts directly to the actuator, reducing response time and saving the cost of tubing brackets and labor.
    • Mounting pattern follows the NAMUR connection standard.
    • Any of the following pilot solenoids will fit the HP series actuator. Simply choose the correct voltage and NEMA rating (if other than 4X)


    Valve Position Limit Switch
    For efficient operation of HP series pneumatic actuators, choose DynaQuip valve position limit switches

    • Provides local or remote indication of valve position
    • Contains 2 SPDT switches
    • NEMA 4, 4X enclosure Additional NEMA ratings and voltages are available.
    • High contrast indicator for instant visual notification.
    • Includes mounting bracket
    • 1/2" NPT conduit entry
