Full welded ball valve is a typical narrow gap submerged arc welding product, which involves the knowledge of materials, welding technology, automatic development of welding equipment and design of pipeline ball valve. The valve seat of full welded ball valve is composed of carbonized Teflon sealing ring and butterfly spring, so it has strong adaptability to pressure and temperature changes.

Application of Full Welded Ball Valve：

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

2. Central heating: output pipeline, trunk line and branch line of large heating equipment;

3. Heat exchanger: opening and closing of pipes and circuits;

4. Steel plant: various fluid pipelines, waste gas discharge pipelines, gas and heat supply pipelines, fuel supply pipelines;

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

Advantages of Full Welded Ball Valve：

1. No external leakage;

2. The machining precision of ball valve is high, and the machining process is tracked and tested by advanced computer detector;

3. The material of the valve body is the same as the pipe, it won’t suffer uneven stress or deformation;

4. Directly buried welded ball valve can be directly buried underground, which greatly saves construction cost 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 machining precision of ball valve is very precise and the operation is light;

7. Small valve body, beautiful appearance;

8. Over 20 years of service life (Under the condition of ensuring the normal operation and use of the valve).

Features of Full Welded Ball Valve：

1. The valve body is welded by steel pipes;

2. Reinforced polytetrafluoroethylene is used as the ball pad;

3. The valve stem adopts explosion-proof design;

4. Temperature range: -60~200℃;

5. Driving mode: manual, worm gear or matching by customer;
