Precautions for the placement and installation of the stop valve: the valve must be placed in a ventilated and dry place, and its sides should be blocked. In order to prevent the valve from rusting and anti-fouling, it is necessary to brush a layer of anti-rust oil on its surface. In addition, the marking on the valve stem must be complete and clear, and the lead seal and cap are indispensable; after installing the globe valve, it must be regularly overhauled, and it is necessary to check whether the seal is worn or not. Check whether the sealing surface is worn and the valve stem. If the above problems are encountered, they must be repaired and replaced. After the replacement, a sealing test must be passed before assembly.
