Electro-Hydraulic Rotary Valve Actuator
Compact. Simple. Versatile. Delivering up to 300,000 in-lbs of torque with an energy efficient motor design.
The E2HR Series is an all-in-one design. No need for separate hydraulic power units and hoses.
The E2HR, Electro-hydraulic Rotary Actuator packs high performance into the smallest possible installation envelope for ¼ turn valve actuating applications. All hydraulic components and sensors are integrated into a single compact manifold block that also houses the actuator and integral oil reservoir.
The control panel can be mounted directly to the manifold block or installed remotely to run multiple units from a single control panel This self-contained actuator can be installed either vertically or horizontally and has no external piping.
