Gate valve precautions

1. The handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.

2. The double disc gate valve should be installed vertically (that is, the valve stem is in the vertical position and the hand wheel is on 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.
