Matters Needing Attention When Repairing The Insulation Ball Valve

1 Piece Threaded Ball Valve is a type of valve, which is the same type as the flange gate valve. The main difference is that its closing part is a sphere, which rotates around the center line of the valve body to open and close. Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of the medium. It is a new type of valve that has been widely used in recent years. The following Liangtai will explain the matters that need to be paid attention to when repairing the insulated ball valve.

Matters that need to be paid attention to when repairing the insulated ball valve are as follows:

1. When the ball valve is in the closed state, there is still pressurized fluid inside the valve body.

2. Before maintenance, release the pipeline pressure and put the valve in the open position.

3. Before maintenance, disconnect the power supply or gas source.

4. Before maintenance, separate the actuator from the bracket.

In addition, it should be noted that the upstream and downstream pipelines of the ball valve must be checked to ensure that the pressure has been relieved before disassembly and disassembly operations can be performed.
