Welded ball valves are widely used in various fields, and their superior quality and high-performance stability cannot be achieved by ordinary cast steel ball valves. The service life of fully welded ball valves is much longer than that of cast steel ball valves.

 

Technical characteristics of welded ball valve:

1. The valve body structure is welded as a whole, and there will be no external leakage.

 

2. The valve seat is composed of PTFE sealing rings and springs, which have strong adaptability to changes in pressure and temperature, and will not cause any leakage within the range of use.

 

3. The anti leakage structure of the valve stem includes one PTFE self sealing gasket and one O-ring at the bottom of the valve stem, with two O-rings and two PTFE gaskets on top to ensure no leakage.

 

4. The valve body material is the same as the pipeline material, and there will be no uneven stress or deformation due to earthquakes or vehicle passing over the ground.

 

5. The valve body is light and easy to insulate.

 

6. Directly buried ball valves can be buried underground without the need to build large valve wells. Only small shallow wells need to be set up on the ground, greatly saving construction costs and project time.

 

7. The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline.

 

The processing accuracy of the sphere is very precise, and the operation is easy without any adverse interference.

 

10. There are two connection methods: welding and flange.

 

11. Operation mode: Handle, gear (vertical/horizontal)
