Shafer Rotary-Vane hidraulic actuators
These quarter-turn actuators are mainly used in pipeline transmission systems, available for isolating ball/plug valves using the energy of the pipeline fluid. The unique 10 year guarantee ensures minimal moving parts (only one pair of rotating plate in the actuator) reliable technology. Available only in double-acting construction, but because the energy stored in tanks the actuator is suitable for multi-cycle operating and the circular hydraulic hand pump allows local safety operation.
In addition to the remote control to actuator can be assembly with automatic Linebreak detection system so beyond the pre-set pressure drop faster than normal pressure loss closes automatically, thus avoid the broken pipe section from further pressure loss. The torque output between 116 and 667 900 Nm. The ambient temperature is between -60C … + 120C.
