The American standard flanged ball valve is a valve that adopts the American standard for production and inspection. It can also be produced in China. At the same time, the American standard flanged ball valve is used more in China. Of course, many people still prefer imported products. Imported is better.
The imported American standard flanged ball valves are actually similar in quality to the domestic ones, and their service life will not be too different. Today we will tell you how to make the service life of the American Standard flanged ball valve longer.
Before use, we can wash the pipeline and the valve body overflow part with water to prevent residual iron filings and other debris from entering the valve body cavity. When the ball valve is in the closed state, there will still be a part of the medium in the valve body, so it needs to bear a certain pressure. Before repairing the ball valve, close the shut-off valve before the ball valve, open the ball valve that needs to be repaired, and release the valve. internal pressure. If it is an electric ball valve or a pneumatic ball valve, the power supply and air supply should be disconnected first. If PTFE is used as the sealing material, the sealing surface of the hard-sealed ball valve is made of metal surfacing. If the pipeline ball valve needs to be cleaned, care should be taken to prevent damage to the sealing ring and leakage during disassembly.
It can be concluded from the above that if we want the American standard flanged ball valve to have a longer service life, we need to use the valve correctly and maintain it reasonably, which can not only improve the work efficiency, but also reduce the maintenance time and save the replacement cost.
