The HEP series electropneumatic valve positioner with built-in LCD display function is a positioning device that converts the 4-20mA current signal output by the controller into the air pressure driving the valve actuator, overcoming the friction force of the valve and the unbalanced force caused by the pressure change of the regulating medium and making the valve precise and stable.
