1. Operate the electrical device to the fully closed position, and use a multimeter to measure the voltage between the intermediate shaft of the valve position potentiometer and the ground. The absolute value of the voltage increases gradually with the opening of the valve.

2. The user can also operate the direction of the electric actuator for a period of time. Due to its difference, adjust the potentiometer to zero and the absolute value of the measured point to zero or less than 2 MV. When the output current signal is 4 mA, the user can operate the electric actuator to the fully open position, so that the output current signal of the 20mA electric regulating valve on the regulating module is also 20mA, This series of adjustment can be completed at one time as long as it is a professional operator.

How to control the flow of pneumatic control valve.

The flow of electric control valve is greatly affected by the valve size. The total flow of our ordinary valve is directly proportional to the adjustable proportion of the valve. Usually, in the application process, if the adjustable proportion changes, great changes will occur.

In the actual use of the regulator, the manual control valve is well applied to the surface of the fluid control valve. It is generally believed that the flow control can control it. It has a good regulation on the sealing performance of the domestic general electric control valve. It is generally believed that the leakage will change greatly. In addition, it also has a good effect when we use it to some extent, Therefore, we can adjust the electric control valve to avoid unnecessary damage or wear.
