Double-acting and spring return electro-hydraulic solutions for on-off valves on heavy duty services, suitable for high pressure supply. Models available for output toques to 60,000Nm.

Features

  • Manifold build reduces risk of oil leakages, eliminating potential leak paths, improving reliability and vibration resistance
  • Easy setting and maintenance
  • Accumulator ensures instantaneous response to commands. Redundant accumulators are available on request
  • Poppet type solenoid valves guarantee tight shutoff with improved energy saving
  • Double relief valve and hydraulic filiters improve reliability, durability and safety while providing protection to motor and system
  • Limit switch box and PST options available
  • Critical parts manufactured from 316 stainless steel as a standard to prevent corrosion 
    • 316 L stainless steel cabinet and oil tank as standard
    • 316 / 316 L stainless steel tubing and fittings
  • Hydraulic manual local control as standard
  • Local and remote operation as standard
  • Lower power comsumption
  • Low numbers of components involved (reduced fail capability)

General Applications

EHA/EHAS electro-hydraulic actuators use a self-contained power unit to provide operation and control of 1/4" turn valves in on-off applications when the primary power source (instrument air or hydraulic supply) is unavailable.
