A hydraulic positioner is a device that takes an electronic signal and converts it into a defined valve or cylinder rod travel.
The Intelligent Hydraulic Positioner (IHP24) from Val Controls can control solenoid operated on/off valves to move an actuator to a requested set point.
This can be modulating open/close, in between function or stepping for choke valves.
The IHP24 is designed specifically for moving hydraulic operated objects. Once installed and configurated the IHP24 auto calibrate and determine the fully open or fully closed state of the obturator.
