Gas all- welded ball valves are widely used in urban gas pipelines,our products advantages:

1.Small construction spece, low construction cost;

2.The operator does not need to enter the well,The valve can be operated with a T-handle on the well, and it's not danger of choking;

3.According to the depth of underground gas pipeline, the valve can be provided with different lengthening height.

Different port connections can be designed;

4.The valve with double diverging structure makes the pipe safer and more convernient for installation,debugging and maintenance.

5.All welded structure, no leakage part, The possibility of maintenance is relatively low, the valve weight is lighter.
