Other Pneumatic Drives

A rotary actuator is an actuator that produces a rotary motion or torque. Widely used (90° rotation angle) with ball valves, butterfly valves in all branches of the industry. 120° or 180° available on request. Single acting actuators use the pressure imparted by compressed air to create a driving force in one direction (usually out), and a spring to return to the „home” position. Double acting actuators use the force of air to move in both extend and retract strokes. They have two ports to allow air in for instroke and outstroke.

Pneumatic grippers

Pneumatic grippers available in single or dual acting versions with a wide diameter range for internal and external clamping. All sizes come with magnets and sensor slots. Clamping force depends on gripping diameter.

Special versions available on request:

  • a) 5 position monitoring using a positionable sensor,
  • b) with spring lock device in case of pressure drop,
  • c) double clamping force with half stroke.

Working pressure:

  • from 1 bar to 10 bar

Working temperature:

  • from +5°C to +85°C

Seal:

  • NBR/POLYURETHANE

Grippers:

  • a) parallel,
  • b) hinged,
  • c) with retracting jaws,
  • d) toggle
