What Is An Insulated Ball Valve And How To Install It?

What is 2 Piece Threaded Ball Valve and its advantages analysis

The insulated ball valve is a valve of the same type as the flange gate valve. The main difference is that the closed part is a sphere. The sphere rotates around the center. A valve that rotates around the center line of the valve body to achieve opening and closing. The insulated ball valve is a relatively new ball valve, and its structure has some advantages, such as no friction in switching, wear resistance, and small opening and closing torque. Ball valves are mainly used to block, distribute and change the flow direction of the medium in the pipeline. The insulated ball valve is a new type of valve that has been widely used in recent years and is generally installed horizontally.

The insulated ball valve is a relatively new type of ball valve, which has the structural advantages of no friction in switching, low wear, and small opening and closing torque. This allows you to reduce the size of the actuator. Equipped with a multi-turn electric actuator, the medium can be adjusted and closed. The insulated ball valve has low fluid resistance, simple structure, compact and reliable, and easy operation and maintenance. Therefore, it is widely used in petroleum, chemical industry, urban water supply and drainage and other working conditions with strict requirements for shutoff.

The installation steps of the insulated ball valve are shown below:

1. Remove the protective covers on both sides of the flange and fully open the valve to flush it.

2. Before installation, the whole machine should be tested according to the specified signal (electric or gas) (to prevent the impact of vibration caused by transportation on performance). Then it can be installed online.

3. Before connecting the pipeline, flush the remaining impurities in the pipeline (these substances will damage the valve seat and ball).

4. During installation, do not use the actuator part of the valve as a lifting point to avoid damage to the actuator and accessories.

5. The insulated ball valve should be installed horizontally or vertically in the pipeline.

6. The pipeline near the installation site should not be suspended or subjected to external forces. You can use a pipe bracket or support to eliminate pipe misalignment.

7. After connecting the pipeline, tighten the flange connection bolts to the specified torque.
