Finally, internal leakage caused by medium scouring and valve aging. After the electric control valve is adjusted and operated for a period of time, the travel of the valve will increase and the valve can not be closed tightly due to cavitation erosion of the valve, medium erosion, wear between the valve core and valve seat, and aging of internal components. The final leakage will increase. With the passage of time, the internal leakage will become more and more serious. The operator shall adjust the actuator and regularly maintain and calibrate it.

The valve body of the ball valve can be either integral or combined. Principle The electric ball valve is composed of a plug type ball valve and an electric actuator. The valve body structure of the ball valve is a valve core that rotates 90 degrees. The electric actuator is a standard signal that inputs 0-10 mA. The motor unit drives the angular torque of the gear worm gear to adjust the valve with a switch box. Its application mainly depends on electric flow and conditioning operation
