Electric valve EVP2001 Type inner intelligent valve positioner is based on the new high-speed low-power Industrial SCM as the core of the intelligent signal acquisition and control unit. This product uses a soft-measurement technology and pulse width modulation (PWM) intelligent control algorithm, can directly receive the output of 4-20mA signals from industrial instrument or computer and electric actuator’s inside plastic potentiometer position feedback signal, use kinds of valves or devices to proceed precise positioning operation. We adopt ring fluorine resin encapsulation, compact and can be mounted directly on the junction box of electric actuator. It can output the rotational angle (or displacement) feedback signal corresponding to the electric actuator. The controller uses three key operation, eight LEDs display the working status of the controller directly, with the function of fault diagnosis, easy to operate.
