① Foreign particles may be caught on the seat surface.
After the installation of the valve, the inside of the pipeline should be flushed with the valve fully opened to remove the foreign particles.② If the valve and the pipe are made of different metals, a cell may be formed because of the potential difference between the metals. This may cause galvanic corrosion inside the valve, leading to the possibility that the handle gets stuck or seat leakage occurs. Use the same material for the valve and the pipes when they are used in the same pipeline.
