1. Before installing a valve, carefully verify that the valve model and specifications match the design.
2. Verify that the valve is suitable for the required application conditions based on the valve model and manufacturer's instructions.
3. When lifting the valve, tie the rope to the flange connection between the valve body and bonnet, and avoid tying it to the handwheel or valve stem to avoid damage to the valve stem or handwheel.
4. When installing the valve on a horizontal pipeline, the valve stem should be vertically upward; do not install the valve stem downward.
5. When installing the valve, do not use forced connection methods such as pulling or pulling to avoid damage due to uneven force.
6. Rising-stem gate valves should not be installed underground in damp locations to prevent valve stem corrosion.
