Repeat the flushing multiple times before starting work; Regularly opening the shut-off valve may result in some dirt on the sealing surface. When closing, it is also necessary to use this method to flush before officially closing. When opening and closing normally, pay attention to using steady force; When opening, the handwheel should be turned back slightly to ensure a tight fit between the threads to prevent loosening. In addition, if the handwheel or handle is missing or damaged, it should be promptly equipped and not replaced with other tools to prevent damage to the valve stem; Some media will cool down after the shut-off valve is closed, so it should be closed again to ensure that there are no gaps on the sealing surface.
