（Resilient Seated Gate Valve Installation & Commissioning）
If the valve is frequently opened and closed, lubricate at least once a month.
All kinds of manual gate valves installed on the thermal insulation pipeline must not handle downwards.
The gate valve with transmission mechanism should be installed in accordance with the product manual.
The hand wheel and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.
The installation position and height must meet the design requirements, and the connection should be firm and tight.
The double gate valve should be installed vertically (the valve stem is in the vertical position and the handwheel is on the top).
The gate valve with bypass valve should be opened before opening (to balance the pressure difference between the inlet and outlet and reduce the opening force).
