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.
