STRUCTURE FEATURES

Welded ball valves are widely used in various fields. Its superior quality and high-performance stability which cannot be achieved by ordinary cast steel ball valves. The service life of fully welded ball valves is much longer than cast steel ball valves. Fully welded ball valves are widely used in city gas. , Urban heating, petrochemical, shipbuilding, steel, pressure regulating stations, power plants and other pipeline equipment.

Technical features:

1. The valve body structure is integrally welded, there will be no external leakage.

2. The valve sea has strong adaptability to pressure and temperature changes, will not cause any leakage within the scope of use.

3. The anti-leakage structure of the valve stem, ensure no leakage.

4. The valve body material is the same as the pipe material, so there will be no uneven stress, and no deformation due to earthquakes or vehicles passing the ground.

5. The valve body is light and easy to keep warm.

6. If the valve is direct-buried ball valve can be directly buried in the ground, instead of building tall valve wells, only small shallow wells are set 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 and easy to operate, without bad interference.

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

11. Mode of operation: handle, worm gear (vertical/horizontal)
