Installation and Daily Maintenance of Stainless Steel Ball Valve

In the valve series, gate valve, globe valve, ball valve, plug valve, butterfly valve, diaphragm valve, etc, are the most common. This series of block valves, also known as closed-circuit valves, are used to connect or block the medium in the pipeline. So what should we do about the installation and maintenance of ball valves?

The installation process of ball valve

1. First of all, it is necessary to check whether the valve model is consistent with the working condition, and pay attention to the connection size and medium flow direction to ensure that the valve requirements are met;
2. It is necessary to carefully check whether there is dirt or sand adhering to the valve inner cavity and sealing surface;
3. Before installing the valve, make sure to reserve the necessary space for valve driving;
4. The valve must be installed vertically, and it cannot be inverted;
5. During installation, the valve disc should be stopped at the closed position;
6. Tighten the bolts of each connecting part evenly to avoid looseness;
7. Check the packing parts carefully, and ensure that the ram can be opened flexibly while ensuring the tightness of the packing;
8. Finally, we can install it according to the installation steps of installation instructions of the purchased valve (each type of valve has its own installation instructions);

How to maintain ball valves?

• 1. The non-metallic parts shall be taken out from the cleaning agent immediately after cleaning, and shall not be soaked for a long time;
• 2. Metal parts can be cleaned with gasoline, and non-metal parts can be cleaned with pure water or alcohol;
• 3. When cleaning, it is necessary to remove all the grease, dirt, glue and dust adhering to the wall;
• 4. When the ball valve is disassembled and reassembled, be careful so that the sealing surface of the parts, especially the non-metallic parts will not be damaged. It is better to use special tools when taking out the O-ring;
• 5. In addition, new parts should be cleaned during assembly;
  6. The grease used shall be compatible with metal materials, rubber parts, plastic parts and working media of ball valve.
• 7. Normal working conditions and harmonious temperature / pressure ratio;
• 8. When the ball valve is closed, there is still pressure fluid inside the valve body. Before maintenance, release the pipeline pressure and the valve should be open;
• 9. The downstream pipeline can only be disassembled after the pressure has been removed;
• 10. If there is micro leakage at the packing, lock the stem nut (do not lock it tightly after the leakage is stopped).
  
  Valves can be seen everywhere in our life, and can be seen in every household. As for the maintenance of the ball valve and some related precautions, you still need to know something about it. Maintenance is very important for long service life of ball valve. A lot of people don’t pay attention to maintenance. When the valve stem began to rust, the switch is inflexible, and even leakage occurs, they just tie it with a rope.
