Precautions For Using Gate Valves

1. The handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is 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. Before opening the gate valve with a bypass valve, the bypass valve should be opened first (to balance the pressure difference between the inlet and outlet and reduce the opening force).
4. Gate valves with transmission mechanisms should be installed according to the product instruction manual.
5. If the valve is frequently used on and off, lubricate it at least once a month.
6. The gate valve is only used to fully open or fully close the medium running on various pipelines or equipment, and is not allowed to be used for throttling.
7. For gate valves with handwheels or handles, no additional auxiliary levers are allowed during operation (if the seal is not tight, the sealing surface or other parts should be inspected and repaired). Turn the handwheel and handle clockwise to turn off, and vice versa to turn on. Gate valves with transmission mechanisms should be used according to the product instructions.
