SSK Actuators – Advanced Valve Control Solutions

Ratchet coupling

Design Features

Design Characteristics

  • repeatable switching for 90° and 120°
  • no special actuator necessary
  • no adjusting
  • no passing of set position
  • sturdy design

Mounted between an actuator and valve plug the actuator torque will be transferred via the ratchet to the valve plug. By running of the actuator in springreturn position the ratchet is in inaction. At the next switchstep the ratchet turns the plug another 90°.

The plug can only turn in one direction! On construction you have to mind, that the opening of the plug passes over the intakes and accordingly the outlet ports. In the process the passing over has to be allowed.
