What are the precautions for the operation of PE ball valve in practical applications

As an important component of the fluid control system, the performance stability and service life of the polyethylene ball valve (PE Ball Valve) directly affect the efficiency and safety of the entire system.

Before installing the PE ball valve, first ensure that the pipeline system is thoroughly cleaned. This process not only includes removing impurities and oil stains in the pipeline, but also requires blowing and cleaning the pipeline to ensure that the sealing performance of the valve is not affected. The sealing effect of the PE ball valve directly depends on the cleanliness of its interior. Any residual impurities may cause damage to the sealing surface, which in turn affects the normal use of the valve.

During the installation process, the position and direction of the valve are also crucial. The PE ball valve should be installed on a horizontal or vertical pipeline, and ensure that its switching direction is consistent with the flow direction of the pipeline. The design of the operating handle should also take into account the convenience of maintenance and avoid installing the valve in a difficult-to-reach position. Using appropriate tools and installation methods to prevent physical damage to the valve during installation is the basis for ensuring the long-term and stable operation of the valve.

In daily operation, operators need to regularly check the switch status of the valve to ensure that it is in the correct position. When opening or closing the valve, the operating handle should be rotated slowly and smoothly to avoid damage to the valve or wear of the sealing surface due to excessive force. During operation, closely observe the sealing performance of the valve. If leakage is found, take immediate measures to deal with it to prevent potential fluid leakage risks.

For PE ball valves that have not been used for a long time, inspection and testing before reactivation cannot be ignored. This includes a comprehensive assessment of the valve's sealing performance, operating flexibility, and signs of damage or wear. During the test, appropriate media and pressure should be used to ensure that the valve can withstand the expected working pressure and temperature to ensure its reliability in actual use.

In terms of maintenance, it is very necessary to regularly clean the dirt and dust on the outside of the valve to keep it neat and beautiful. At the same time, the sealing surface and operating mechanism of the valve need to be inspected. If wear or damage is found, the relevant parts should be replaced in time. In addition, for lubricated valves, regular addition of lubricant will help maintain the operating flexibility of the valve and prevent sticking due to insufficient lubrication.
