What are the appropriate operating steps for the valve?
The valve is in the liquid system software. The mechanical equipment used to manipulate the position, working pressure, and total flow of the liquid is the mechanical equipment that allows the fluidity or termination of the compound in the electrical wiring and industrial equipment and can manipulate the total flow.

2. Moderate operation steps of the valve
The valve has undergone a pressure test and uniformity before installation. When the valve is operating for a long time, the personnel in the operation process should pay attention to the inspection of the valve. During the inspection, the person bypasses the valve import and export trade, inspects the valve seal, pulls the valve of the wrench by hand, and opens it once a period of time.
