In order to make the performance of the ball valve stable and long-lived, you need to pay attention to the following factors:
1. Before use, apply water to clean the pipe and the over-flow part of the valve body to prevent residual iron filings and other debris from entering the valve body cavity.
2. When the ball valve is closed, some of the medium remains in the valve body and is also subjected to a certain pressure. Before servicing the ball valve, close the shut-off valve before the ball valve, open the ball valve that needs to be repaired, and completely release the internal pressure of the valve body. In the case of electric ball valves or pneumatic ball valves, the power and air supply should be disconnected first.
3. Generally, soft-sealed ball valves use PTFE as a sealing material, and the sealing surface of the hard-sealed ball valve is made of metal. If the pipe ball valve needs to be cleaned, care should be taken to prevent damage to the seal ring and leak during disassembly.
