The AVAMO ASEH heavy duty self-contained electro-hydraulic Scotch Yoke actuators have been developed for both on/off or modulating operations and are available as a single- or double-acting version. ASEH actuator solutions are used when there is only electrical power available. The actuators operate ball, butterfly or plug valves with torque up to 600.000 Nm. Our standard version consists of a compact and maintenance-free design with a SMART Control Unit. The SMART Control Unit is ready for hardwired communication as well as for MODBUS or Profibus communication.
The actuator is designed for longevity, ensured by bronze slide blocks and nickel or Ionit Ox plated cylinders. Chromium plated rods and custom paint jobs provide an excellent protection against corrosion.
