What is a inner intelligent valve positioner?
EVP2001 Type inner intelligent valve positioner
The electric valve EVP2001 intelligent control 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, which can directly receive the output of 4-20mA signals from an 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 the electric actuator. It can output the rotational angle (or displacement) feedback signal corresponding to the electric actuator. The controller uses three key operations, eight LEDs display the working status of the controller directly, with the function of fault diagnosis, easy to operate.
