Product introduction:

Extended stem ball valve buried design. Buried ball valve, the valve stem can be lengthened according to the needs of the project, so that it can be operated on the ground, and the corresponding grease injection, sewage and exhaust devices are extended from the pipe to the ground.

Extended stem ball valve ball valve includes floating ball valve and trunnion ball valve. Large-diameter direct-buried all-welded ball valve generally uses trunnion welded ball valve, trunnion welded ball valve, and the ball is fixed on the upper and lower sides of the ball to ensure the valve is opened and closed. Stability,

features:

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

2. The valve seat is made up 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 and the bottom of the valve stem have a PTFE self-sealing gasket and an O-ring. 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, and there will be no uneven stress and no deformation due to earthquake and vehicle passing through the ground.

5, the valve body is light and easy to keep warm.

6. Extended stem 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 cost 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 precision of the sphere is very precise and easy to operate, without any interference.

10. There are two connection methods of welding and flange.
