Plug Valve Installation And Maintenance

When installing the 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 paid attention to:
1. Make sure the valve is open. Heat the pipe first. Transfer as much heat as possible from the pipe to the stopcock. Avoid prolonging the heating time of the plug valve itself.
2. Use gauze or wire brush to clean the pipes and cut parts to make the metal surface shiny. Steel wool is not recommended.
3. First cut the pipe along the vertical direction, trim and remove the burrs, and measure the diameter of the pipe.
4. Apply flux to the outside of the pipe and the inside of the welding shield, the flux must completely cover the welding surface. Please use flux sparingly.
