How does the actuator structure diagram of pneumatic butterfly valve work? Since the electric three-way butterfly valve is so excellent, there is naturally a great demand in the market. There is a great demand for electric three-way butterfly valve in the water supply, metallurgy, textile, energy and even paper industries. So what should these industries pay attention to when purchasing electric three-way butterfly valve?
、 Finally, internal leakage caused by medium scouring and valve aging. After the pneumatic butterfly 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 the cavitation of the valve, the erosion of the medium, the wear between the valve core and the valve seat, and the aging of the 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.
