The E2H Series is an all-in-one design for linear control valve automation. No need for separate & bulky hydraulic power units and hoses.

The E2H, Electro-hydraulic Actuator for linear valve automation packs high performance into the smallest possible installation envelope for linear valve actuating applications.

All hydraulic components and sensors are integrated into a single compact manifold block that also houses the linear 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.
