The Rotork Fluid Systems EH Range of self-contained, electro-hydraulic actuators include an integrated control module; a hydraulic manifold; and a power unit consisting of a motor, hydraulic pump and reservoir. EH actuators are available in double-acting or spring-return, fail-safe configurations for both quarter-turn and linear applications. They can be configured to mount in any position, including remote mounting of the control module. Torque requirements up to 600,000 Nm (5.3 million in lbs) and thrusts up to 5,500,000 N (1,236,500 lbs) can be accommodated. All electronics are protected in a watertight or explosion-proof enclosure.
