When installing the plug valve, in order to prevent damage to the plug valve and to ensure full play of the working performance of the plug valve, the following four points should be noted:
1. Make sure the valve is open. Heat the pipe first. Transfer as much heat as possible from the pipe to the plug valve. Avoid prolonging the heating time of the plug valve itself.
2. Use gauze or wire brush to remove the pipe and cutting parts to make the metal surface shine. Steel wool is not recommended.
3. First cut the pipe in the vertical direction, trim and remove the burrs, and measure the pipe diameter.
4. Apply flux to the outside of the pipe and the inside of the soldering cover. The flux must completely cover the soldering surface. Please use flux in a controlled manner.
