The Rotork EH Pro 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 configurations for both quarter-
turn and linear applications.
They can be configured to mount in any position, including remote
mounting of the control module and/or hydraulic power unit (HPU). Torque
requirements up to 600,000 Nm (5.3 million lbf-in) and thrusts up to
5,500,000 N (1.2 million lbs) can be accommodated.
All electronics are protected in a watertight or explosion-proof enclosure.
Other features include local manual control, indication feedback via
dry contacts and 4-20 mA signal; or optional digital control via Modbus,
Foundation Fieldbus, Profibus, DeviceNet or Rotork Pakscan communication
systems. The EH Range can be supplied for operation with virtually any
single phase, three phase, or 24 VDC power supply.
