1. Purpose of fully welded ball valve:

1. Urban gas: gas output pipeline, main line and branch line supply pipeline, etc.

2. Central heating: output pipelines, trunk lines and branch lines of large heating equipment.

3. Heat exchange: opening and closing of pipelines and circuits.

4. Steel works: various fluid pipes, exhaust pipes, gas and heat supply pipes, fuel supply pipes.

5. Various industrial equipment: various heat treatment pipes, various industrial gas and heat pipes.


2. Fully welded ball valve product description:

1. Q367F fully welded ball valve will not have external leakage and other phenomena.

2. The processing process of the sphere is tracked and detected by advanced computer detector, so the processing accuracy of the sphere is high.

3. As the material of the valve body is the same as that of the pipe, the stress will not be uneven, and the deformation will not occur due to the earthquake and the vehicle passing through the ground, so the pipe is resistant to aging.

4. The body of the sealing ring is made of RPTFE with 25%Carbon to ensure no leakage (0%).

5, directly buried type welding ball valve can be directly buried in the ground, there is no need to build a large valve well, only small shallow Wells on the ground, greatly save construction costs and engineering time.

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

7, the ball processing precision is very precise, easy to operate, no adverse interference.

8. The use of advanced raw materials can ensure the pressure above PN25.

9. Compared with the same specification products in the same industry, the valve body is small and beautiful in appearance.

10. The service life of the valve shall be more than 15 years under normal operation and use conditions.
