3.The valve that has been assembled should be maintained periodically to ensure its function.
4.The sealing surface should be maintained or replaced when it was abraded.
5.Check the trapezoid thread’s wear condition in the bolt and nut, and check the filler aging. It should be replaced when it is necessary.
