Directly buried standard diameter all welded ball valve:

 

● Product Overview:

 

1. The buildings, roads and vehicles in modern cities are complex, pedestrians are dense, and the road conditions are very complicated. Therefore, the construction time and construction safety requirements are very high when constructing and maintaining the heat and gas supply pipelines. The welded ball valve minimizes the space occupied by the valve control and saves construction costs and engineering time.

 

2. Directly buried all-welded 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 costs and engineering time.

 

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

 

4. When the direct-buried ball valve is opened and closed, the operator does not need to enter the underground, and only needs to carry out the transmission operation on the ground, and the operation is very safe and convenient.

6. Extension rod: carbon steel

 

● Direct buried all-welded ball valve technical features:

 

1): The direct-buried all-welded ball valve is integrally welded without external leakage.

 

2): Directly buried all-welded ball valve Because the seat is made of carbonized Teflon seal ring and compensating spring, it has strong adaptability to pressure and temperature changes, and does not produce any slippage within the marked pressure and temperature range. .

 

3): The processing process of the direct-buried all-welded ball valve ball has advanced computer detector tracking detection, so the processing precision of the ball is high.

 

4): The direct-buried all-welded ball valve has the same material as the pipe material, and there is no uneven stress, and it will not be deformed due to earthquakes and vehicles passing through the ground. The pipeline is resistant to aging.

 

5): The sealing ring body is made of PTFE with a content of 20% C (carbon) to ensure no leakage (0%).

 

6): Directly buried all-welded 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 costs and engineering time.

 

7): Directly buried all-welded ball valve can adjust the length of the valve body and the height of the valve stem according to the construction and design requirements of the pipeline.
