1. When closing or opening valves, it is prohibited to use long levers or long wrench wheels.

2. The thread of the valve stem often rubs against the valve stem nut, and a certain amount of oil should be maintained at the screw to provide lubrication and ensure the free movement and flexibility of the valve stem. When the valve system is mechanically driven, it is necessary to add additives to the gearbox in a timely manner to prevent biting.

3. Valves that have been open for a long time may have dirt adhering to their sealing surfaces; When closing, gently close the valve first, then open it a little, so that the high-speed flowing medium can be used to flush away the dirt, and then close it tightly.

4. Electric concealed stem gate valves installed outdoors should be protected by a protective sleeve on the valve stem to prevent rain, snow, dust, and rust.

5. Valves should be regularly cleaned and inspected to maintain the cleanliness and integrity of all components. Do not place heavy objects on the valve, let alone stand on it.

6. Before opening the steam valve, the condensate in the system must be drained first, and then the valve should be slowly opened to avoid steam water impact; When the valve is fully open, the handwheel should be turned back slightly.

7. Backup valves should be placed indoors in a dry place and sealed with wax cardboard or plugs to prevent dirt from entering.
