Pneumatic Actuators

BI-TORQ Valve Automation offers three styles of rack and pinion pneumatic actuators in double acting and spring return models up to 57,000 inch pounds torque. All of our pneumatic actuators feature ISO and NAMUR mounting to meet international standards and allow for simple installation of solenoids, limit switches, positioners and other automation accessories. With body material options in hard anodized extruded aluminum (our PN Series), heavy duty polyester powder coated aluminum (our AL Series), or stainless steel, we offer quarter-turn pneumatic actuators to fit virtually any application.
