Troubleshooting of soft seal gate valve
The soft-seal gate valve is powered by compressed air, and the ball rod drives the ball to rotate 90 degrees to achieve a fully open-fully closed action. Valve seat form: T, F, C type. Its supporting accessories include air filtration and decompression Valves, limit switches, solenoid valves. Among them, the main function of the air filter pressure reducing valve is to stabilize the pressure, filter impurities and water vapor in the air. The fault that often occurs during the use of the valve is air leakage. The following briefly introduces the valve Common faults and corresponding maintenance methods.

Working principle of pressure reducing valve
The pressure reducing valve is a special device that automatically reduces the working pressure of the pipeline. It can reduce the higher water pressure in the pipeline before the valve to the level required by the pipeline after the valve. Pressure reducing valves are widely used in high-rise buildings, areas where the water pressure of the urban water supply pipe network is too high, mines and other occasions to obtain appropriate service water pressure and flow at each water point in the water supply system. In view of the fact that the water leakage rate and the degree of waste are almost proportional to the water pressure of the water supply system, the pressure reducing valve has system operating conditions and potential water saving effects. According to statistics, its water saving effect is about 30%. In order to adjust the level of accuracy, this valve has a good installation effect.
