1.Compact structure, reasonable design, good valve rigidity, smooth passage.
2.The use of flexible graphite packing, reliable sealing, light and flexible operation
Industrial applications: Petroleum, Chemical, Paper Making, Fertilizer, Coal Mining,Water treatment and etc.
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.
