Technical features of welded ball valve:

The valve body structure is integrally welded, without external leakage.

 

The valve seat is composed of PTFE sealing ring and spring, which has strong adaptability to pressure and temperature changes and will not cause any leakage within the use range.

 

Anti-leakage structure of the valve stem: there is one PTFE self-sealing gasket and one O seal ring at the bottom of the valve stem, and there are two O seals and two PTFE seals on the top to ensure no leakage.

 

The material of the valve body is the same as that of the pipe, so there will be no uneven stress and no extrusion deformation due to earthquake and when the vehicle passes through the ground.

 

The valve body is light and easy to be insulated.

 

The directly buried ball valve can be directly buried underground, without building a large valve well, and only a small shallow well needs to be set on the ground, greatly saving construction costs and project time.

 

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 machining accuracy of the sphere is very precise and easy to operate without poor interference.

 

Welding and flange connection modes are available.

 

Operating mode: handle, gear (vertical/horizontal)
