1. The servo amplifier adopts deep dynamic negative feedback, which can improve the accuracy of automatic adjustment.

2. Electric operators come in various forms and are suitable for 4~20mA. DC or 0~10mA.DC.

3. The adjustable range is large, the inherent adjustable ratio is 50, and the flow characteristics include straight line and equal percentage.

4. The electronic electric control valve can directly control the valve opening by current signals without the need for a servo amplifier.

5. The valve body is designed according to the principle of fluid mechanics with a low-flow resistance passage of equal cross-section, and the rated flow coefficient is increased by 30%.

The electric regulating valve automatically controls the opening of the valve according to the signal from the regulating part, thereby regulating the medium flow, pressure and liquid level. Taking the most commonly used 4-20mA current signal as an example, when the signal from the control system to the electric control valve is 4mA, the control valve is in a fully closed state, and when a 20mA signal is given to it, the control valve is in a fully open state. Different signal values between 4-20mA correspond to different openings of the regulating valve, that is, when the control system gives it a 12mA signal, the opening of the regulating valve is 50%. Select the applicable flow coefficient according to your own working condition medium, and you can calculate the flow rate and pressure corresponding to each opening of the regulating valve. In order to achieve the regulation requirements of the regulating valve for the working medium.
