1. The valve body structure is welded integrally, and there will be no external leakage.
2. The valve seat is composed of PTFE sealing ring and spring, which has strong adaptability to the changes of pressure and temperature, and will not produce any leakage within the scope of use.
3. The anti leakage structure of the valve rod has a PTFE self sealing gasket and an O-ring at the bottom of the valve rod, which is composed of a 2O ring and two PTFE gaskets to ensure no leakage.
4. The material of the valve body is the same as that of the pipeline, so there will be no uneven stress, and there will be no compression deformation due to earthquake and vehicles passing the ground.
5. The valve body is light and easy to keep warm.
6. The directly buried ball valve can be directly buried underground without building a large valve well, but only a small shallow well on the ground, which greatly saves construction costs and engineering 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.
8. The machining accuracy of the sphere is very precise, the operation is light, and there is no adverse interference.
9. There are two connection modes: welding and flange.
10. Operation mode: handle, gear (vertical / horizontal)
