1. The valve body structure is welded integrally without any external leakage.
2. The valve seat is composed of PTFE sealing ring and spring. It has strong adaptability to pressure and temperature changes and will not cause any leakage within the scope of use.
3. The anti-leakage structure of the valve stem, the bottom of the valve stem has a PTFE self-sealing gasket and an O-ring seal. The top has two O-rings and two PTFE gaskets to ensure no leakage.
4. The valve body material is the same as the pipe material, there will be no uneven stress, and it will not be deformed due to earthquake and vehicle passing through the ground.
5. The valve body is light and easy to keep warm.
6. The direct-buried ball valve can be buried directly in the ground. It is not necessary to build a large valve well. It only needs to set up 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 processing accuracy of the ball is very precise and easy to operate, no adverse interference.
10. There are two connection methods of welding and flange.
11, operating mode: handle, gear (vertical / horizontal)
12. In the case of normal operation of the valve, the warranty period is 20 years.
