1. Before valve installation, carefully verify that the valve model and specifications match the design.
2. Check the valve's compatibility with the required conditions according to its model and manufacturer's instructions.
3. When hoisting valves, ropes should be tied to the flange connection between the valve body and cover, and not to the handwheel or valve stem to avoid damage.
4. When installing valves on horizontal pipelines, the valve stem should be vertically upward; downward installation is not permitted.
5. Do not force the valves by pulling or dragging during installation to avoid damage due to uneven stress.
6. Rising stem gate valves should not be installed in damp underground locations to prevent valve stem corrosion.
