The electric angle regulating valve is powered by a single-phase AC 220V power supply and receives a 0-10mA DC signal to automatically control the valve opening, thereby achieving continuous adjustment of process parameters such as pressure, temperature, flow rate, and liquid level. It is an important link in the automatic adjustment system of the production process,Angle type regulating valve is composed of an electric actuator and a regulating valve that are mechanically connected, assembled, debugged, and initially assembled. The DC current signal sent by the input transmitter of the electric angle regulating valve is amplified by the servo amplifier to drive the actuator, generating axial thrust and driving the regulating valve to act, thereby causing changes in the medium flow rate, thus achieving various thermal processes in the regulating system. At the same time, the actuator sends a valve displacement signal for the servo amplifier to compare, so that the regulating valve always remains in the position corresponding to the input signal, completing the servo adjustment task.

The interface direction of the angle valve is different from that of the straight through valve, and the installation size, flow direction, flow coefficient, and allowable pressure difference should be checked; The proximity of the elbow positions on site does not necessarily mean that they can be directly replaced. It is also necessary to check the pipeline support and actuator maintenance space.
It is necessary to confirm the control input, valve position feedback, power or gas source conditions, interfaces, and fault location separately. Input and feedback are not the same function, and it cannot be assumed that all analog signals or communication protocols are fully equipped based solely on the name "regulating type".
The power-off action cannot be determined solely by the name of the electric drive. Ordinary electric actuator cannot default to having automatic valve closing function when power is lost; If the process requires fault closure, the energy storage or other fault safety scheme of the actuator should be confirmed at the time of ordering, and the entire valve interlock verification should be completed.
