HEP15/16/17  Electro-Pneumatic Positioner is a main accessory of the control valves, designed for use with pneumatic diaphragm actuators.

HEP15/16/17 single-acting electro-pneumatic valve positioner uses the principle of force balance to convert the electrical signal output by the regulator into a pneumatic signal that drives the regulating valve, thereby ensuring that the regulating valve presses the regulator’s output signal quickly and accurately. Positioning; at the same time, it can also change the flow characteristics or action mode of the regulating valve.
