The following should be paid attention to when installing and maintaining gate valves: hand wheel, handle and transmission are not allowed to make lifting, and collision is strictly prohibited. Double-gate-plate valve should be vertically installed (valve stem is in the vertical position and the hand wheel is at the top).
