The EH-2140 Series Linear Electro-Hydraulic actuator produces a high amount of thrust in a small package, with all electronics built-in. The internal construction makes this a leak-proof system. This actuator is ideally suited for modulating or onoff control of all types of globe valves.
These actuators combine the precision of hydraulic controls with the reliability of spring power for simplicity of operation.
They are available in the same small package with spring return for fail-safe to close or open on loss of power.
The EH-2140 Series accepts an analog command signal to accurately position the actuator while providing maximum resolution and speed of response. With resolution better than 0.25%, these actuators offer superior control when compared to conventional electric or pneumatic actuators.
