The ball valve is a universal valve widely used in the valve. It is used in large quantities and consumed quickly. Therefore, reasonable maintenance can improve work efficiency, reduce maintenance time and save replacement costs. Below, BKH Ball Valves/BKH3K Ball Valves Exporter introduces the strategy of using ball valves:

1. Before use, water should be used to clean the pipeline and the 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, there is still some medium in the valve body, and it is also under certain pressure. Before overhauling the ball valve, first close the shut-off valve in front of the ball valve, open the ball valve that needs to be overhauled, and completely release the internal pressure of the valve body. If it is an electric ball valve or a pneumatic ball valve, the power and air supply should be disconnected first.

3. Generally, soft-sealed ball valves use PTFE as the sealing material, and the sealing surface of hard-sealed ball valves is made of metal surfacing. If the pipe ball valve needs to be cleaned, care must be taken to prevent damage to the sealing ring and leakage during disassembly.

4. When disassembling the flanged ball valve, the bolts and nuts on the flange should be fixed first, then all the nuts should be tightened slightly, and finally fixed firmly. If the individual nuts are forcibly fixed first, and then the other nuts are fixed, the uneven lining between the flange surfaces will cause damage or rupture of the cushion surface, resulting in leakage of the medium out of the valve flange.

5. If the valve is cleaned, the solvent used must not conflict with the parts to be cleaned and not corrode. If it is a special ball valve for gas, it can be cleaned with gasoline. Other parts can generally be cleaned with middle water. When cleaning, thoroughly clean the remaining dust, oil, and other attachments. If it can't be cleaned with clean water, it can be cleaned with alcohol and other cleaning agents on the premise of not damaging the valve body and parts. After cleaning, wait for the cleaning agent to evaporate thoroughly before proceeding with assembly.

6. If a slight leakage is found at the packing during use, the stem nut can be tightened slightly until the leakage stops, and no further tightening is allowed.

7. Long-term storage in the open air will cause corrosion of the valve body and parts and impermanent use. When the ball valve is stored, it should be rainproof, waterproof, and moisture-proof, and the flange cover should be tightly covered. Valves stored for more than 12 months should be re-tested during use to ensure stable performance.
