Installation and Maintenance of American Standard Plug Valves

When installing the American standard plug valve, in order to prevent damage to the plug valve and ensure the full performance of the plug valve, the following four points should be noted:

1. Ensure that the valve is in an open state. Heat the pipeline first. Transfer as much heat as possible from the pipeline to the plug valve. Avoid extending the heating time of the plug valve itself.

2. Use gauze or wire brush to remove pipes and cutting areas, making their metal surfaces shiny and shiny. It is recommended not to use steel velvet.

3. Firstly, cut the pipeline in a vertical direction, trim and remove burrs, and measure the pipe diameter.

4. Apply flux to the outside of the pipeline and the inside of the welding cover, and the flux must completely cover the welding surface. Please use soldering flux with moderation.
