Features
1. The processing of the sphere is tracked and tested by an advanced computer detector; the accuracy of the sphere is very high.
2. The material of the valve body is the same as that of the pipeline, there will be no uneven stress, no deformation due to shakes and vehicles passing through the ground, and the pipeline is resistant to aging.
3. The seal ring body is made of 25% Carbon (carbon) RPTFE material to ensure no leakage (0%).
4. The submerged welded ball valve can be directly buried in the ground, without the need to build a large valve well, only a small shallow well on the ground is needed, which greatly saves construction costs and engineering time.
5. 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
6. The processing accuracy of the sphere is very precise, the operation is light, and there is no bad interference.
7. Using high-grade raw materials, it can keep the pressure above PN25.
8. Compared with products of the same specifications in the same industry, the valve body is small and the appearance is beautiful.
9. Under the condition that the valve is normally operated and used, the service life is long.
