Product Introduction

The EPP2000 series electrical valve positioner is used in conjunction with pneumatic actuators to convert input 4-20mADC signals into output air pressure and control the action of the actuator. At the same time, feedback is provided based on the stroke of the actuator, so that the stroke of the actuator can be accurately positioned according to the control signal.
