What do you need to know about electro hydraulic control?
As specialist manufacturers of electro-hydraulic actuation and control equipment we offer comprehensive, purpose designed, engineered and manufactured solutions for the operation of choke and control valves for on-shore and off-shore installations.
How does an electro-hydraulic actuator system work?
How does an electro-hydraulic actuator work? A flapper-nozzle system controls the pressures within the double-acting hydraulic cylinder through a special hydraulic high-pressure valve until the desired position of the valve stem is reached. This results in a proportional relationship between the input signal and valve travel (control valve stroke).
How is feedback used in a hydraulic system?
When feedback inputs are used the system is described as “closed loop.” This is the brains of the electronic control. It processes the inputs and converts them into a defined output to the hydraulic system.
Can a hydraulic controller be factory programmable?
The controller can be factory-programmed or have the ability to be user-programmable to meet the specific needs of the application. Outputs can be on/off voltage signals or proportional PWM signals to control the hydraulic valving.

What is electro-hydraulic stepping actuator used for?
The electro-hydraulic stepping actuator provides a low-cost effective alternative solution to the mechanical ratchet style mechanisms that are occasionally used for choke control. This feature may be incorporated in all versions of hydraulic and electro-hydraulic modulating control options.
