Best wishes for a wonderful holiday season!

Our offices will be closed the week of Christmas, from December 23 – 27, 2024 to allow our team to celebrate with loved ones. We will reopen December 30.

Thank you for your understanding.

Pneumatic Actuators and Accessories

DynaQuip Controls HP Series Rack & Pinion Pneumatic Actuators are designed to meet the needs of the quarter-turn valve market. Engineered to be compact, durable,and versatile, these actuators represent the latest technology coupled with economical and long-lasting operation. Our HP Series actuators are available in double acting and spring return models with torque outputs up to 83,462 inch-pounds with a 80 PSI air supply.

HP Series actuators are perfect for quarter-turn valve automation applications where continuous rapid cycling is required or hazardous conditions exist

Solenoid Pilot Valve
For efficient operation of DynaQuip 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 DynaQuip pneumatic actuators. Simply choose the correct voltage and NEMA rating (if other than 4X)


Valve Position Limit Switch
For local/ remote position indication from DynaQuip 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
