E2H Series
Electro-Hydraulic Actuator
Compact. Simple. Versatile. Delivering thrust up to 500,000 Lbf and equipped with an energy efficient motor design for linear control valve automation.
The E2H Series is an all-in-one design for linear control valve automation. No need for separate & bulky hydraulic power units and hoses.
All hydraulic components and sensors are integrated into a single compact manifold block that also houses the linear actuator and integral oil reservoir.
