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.

The Panel Design

electro-hydraulic actuator control panel
Main Panel: The E2H electro-hydraulic actuator control panel comes standard with touch screen* for quick setup and easy operation. The panel can be mounted remotely or on your E2H.

In addition, you can operate your E2H locally using the physical buttons on the front of the panel.

electro hydraulic actuator status screen
Status Screen: The E2H status screen gives you a quick overview of your system status. Available from the touch screen* or via Ethernet.

Operate Your E2H Remotely Using Our Remote Panel Option

multiple electro-hydraulic actuators
  • The control panel on the electro-hydraulic actuator can be mounted remotely and control multiple valves.
  • It’s ideal for hazardous area locations.
  • It gives you the flexibility to mount the control panel in a safe zone thereby providing a significant cost saving.
  • Access valve performance data for multiple valves from one control panel.
  • Designed to suit your installation.
