PNEUMATIC ROTARY ACTUATORS

HIGH PERFORMANCE AND DURABILITY

SMART IN FLOW CONTROL

Our pneumatic diaphragm actuators are available in various designs. What they all have in common is their high running performance and long service life.
The design of the actuators enables very fine and precise control.
Due to the combination of several spring assemblies or reinforced springs and the mounted piston rod (actuator spindle), even the transmission of high torques is no problem.A quick-acting function is optionally available for all versions. All actuators are suitable for hazardous areas.

Design features

  • Robust and compact
  • Variable number of springs
  • Optimized spring ranges
  • Display of the setting range
  • Mounting of additional devices according to VDI VDE 3845-1 or VDI VDE 3847-2
  • Attachment according to DIN EN ISO 5211 (AT, BR31a, R, S)
  • Signal pressure connection according to EN 15714-3 and VDI/VDE 3845-1
  • Modular design - optionally with manual override, accessories and mechanical end stop screws
  • Reversible rotary action without additional components
