The following small details must be noted when piping valves are installed

1. The valve body material of the valve is mostly made of cast iron, which is brittle and therefore must not be hit by heavy objects.
2. When carrying the valve, it is not allowed to throw it at hand; when lifting and lifting the valve, the rope should be attached to the valve body, and it is strictly prohibited to lie on the hand wheel, the valve stem and the flange bolt hole.
3. The valve should be installed in the most convenient place for operation, maintenance and overhaul. It is strictly prohibited to be buried underground. The valves on the pipes directly buried and in the trench shall be inspected to facilitate the opening and closing and adjustment of the valves.
4. The thread should be intact and wrapped around the thread, leaded with lead oil or wrapped with Teflon tape. When turning the buckle, use a wrench to clamp the hexagonal valve body screwed into one end of the pipe.
5. When installing the flange valve, pay attention to tighten the connecting bolt in the diagonal direction. When the screwing is used, the force should be even to prevent the gasket from running off or causing deformation and damage of the valve body.
6. The valve should remain closed during installation. For threaded valves that are closer to the wall, it is often necessary to remove the stem valve disc and handwheel to install. When disassembling, the handwheel should be turned to keep the valve open, and then disassembled.
