1 EH Range Technica Data Eectro-hydrauic Vave Actuators Redefining Fow Contro

2 EH Range Technica Data INTRODUCTION The Rotork EH Range of sef-contained, eectro-hydrauic actuator incudes an integrated contro modue; a hydrauic manifod; and a power unit consisting of a motor, hydrauic pump and reservoir. A eectronics are protected in a watertight or exposion-proof encosure. EH actuators are avaiabe in doube-acting or spring-return configurations for both quarter-turn and inear appications. They can be configured to mount in any position, incuding remote mounting of the contro modue. Torque requirements up to 600,000 Nm (5.3 miion bf-in) and thrusts up to 5,500,000 N (1,2 miion bf) can be accommodated. Other features incude oca manua contro, indication feedback via dry contacts and 4-20 ma signa; or optiona digita contro via Modbus, Foundation Fiedbus, Profibus, DeviceNet or Rotork Pakscan communication systems. The EH Range can be suppied for operation with virtuay any singe phase, three phase, or 24 VDC power suppy. EH systems can aso operated with an existing hydrauic power unit. The HPU must operate with compatibe hydrauic fuid at pressures that do not exceed EH Range maximums. Consut Rotork Fuid Systems for sizing and appication assistance.
