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.
electro-hydraulic
features
EH
actuators are now enhanced with proven technology from
the IQ range of electric actuators. A host of new operational
and monitoring features include:
Configuration; diagnostics;
fault indication; and position indication via a digital
display and infrared remote.
On/Off; ESD (Emergency shut down);
or positioning with better than 0.5% accuracy.
Improved
safety and reliability - compatibility with SIL3
applications.
Partial stroke capability.
Input power options for virtually
any single or three-phase voltage as well as 24 VDC.
Optional digital control via
Rotork Pakscan, Profibus, Foundation Fieldbus, Modbus
or DeviceNet communication systems.
