Hydraulic Rotary Actuators

Pleiger rotary actuators are specially developed for the operation of butterfly and ball valves. Pleiger rack and pinion actuators type STK are available in double and single design. The Pleiger STK actuators are designed to operate in any enviroment, even submerged or in hazardous areas. In emergency cases all actuators can be operated by hand pump. Pleiger hydraulic actuators provide continuous output over the full quater turn.
