Precautions For Using Gate Valves

1. Handwheels, handles and transmission mechanisms are not allowed to be used for lifting, and collisions are strictly prohibited.
2. The double-gate gate valve should be installed vertically (that is, the valve stem is in a vertical position and the handwheel is at the top).
3. The gate valve with a bypass valve should be opened before opening the bypass valve (to balance the pressure difference between the inlet and outlet and reduce the opening force).
4. The gate valve with transmission mechanism shall be installed according to the provisions of the product instruction manual.
5. If the valve is often used on and off, it must be lubricated at least once a month.
6. Gate valves are only used for fully open and fully closed medium operation on various pipelines or equipment, and are not allowed to be used for throttling.
7. For gate valves with handwheels or handles, no auxiliary levers should be added during operation (if the seal is not tight, check and repair the sealing surface or other parts). The hand wheel and the handle are turned clockwise to close, and vice versa to open. The gate valve with transmission mechanism should be used according to the product instruction manual.
