Flat Gate Valve Use, Maintenance, Care And Precautions

1. The valves have been tested for strength and sealing before leaving the factory, and all connections should remain in their initial state during use.
2. The operating handwheel of this series of valves is marked with an opening and closing rotation direction mark, and the upper part of the rising pole type is equipped with an opening and closing height scale for adjustment instructions.
3. When welding this valve to the pipeline, the valve should be opened, and the neck should be properly protected with moisture to minimize high-temperature heat conduction to prevent damage to the sealing packing.
4. It is strictly forbidden to use the booster rod when closing the valve. When the gate is closed to the top, the handwheel should be rotated 1/2 turn to make the gate in a floating state.
5. During the use of the valve, a certain amount of grease should be injected into the bonnet grease joint regularly.
6. During use of the valve, if it leaks due to wearing parts, it should be replaced in time.
7. During the maintenance process of the valve, the inner cavity should be cleaned, and each transmission part should be greased during assembly.
8. During the storage and out-of-use period of the valve, the gate should be kept in the closed position. For long-term storage, it should be placed in a ventilated and dry place, and should be inspected and maintained regularly.
