DEA Electro-Hydraulic Actuators

Buillt to withstand any environment with precision and power

DEA Electro-Hydraulic Actuators

Versatile & Reliable

An adjustable range of thrust and speed allow the DEA actuators to deliver on a wide variety of functions across your site.

Built Tough

All DEA actuators are completely repairable and made to withstand the toughest operating conditions as they have for the past 50 years.

Plug & Play

The self-contained unit is compact and easy to install into existing setups meaning no need for expensive commissions.

Basic Operation

The DEA Range of Elram Electro-Hydraulic Actuators operates on a simple ‘Bi-directional motor’ principle.

Rotation of the motor causes the actuator to extend or to retract. When the motor is not running the actuator is stationary.

• The actuator may be stopped in any position
• Various hydraulic circuit configurations are available
• Fully-sealed housing
• Solenoid-operated versions are available for applications requiring high-frequency or modulating duty
• “Locked” or “Free-to-move” configurations are available when the motor is running
