Buried Fully Welded Ball Valve

We are engaged in manufacturing and exporting excellent quality Buried Fully Welded Ball Valve in Shijiazhuang Hebei China. Directly buried type full welded ball valve compared with ordinary valve normal need to connect the valve and pipe flange screw gaskets valve and pipe connection spend a large amount of material resources is not conducive to the global environment and energy conservation and emissions reduction.And straight type full welded ball valve without flange bolts gaskets in the form of welding and pipes.Good sealing easy to operate.

Advantage of directly buried type of full welded ball valve:
1 Straight type full welded ball valve can be directly buried in the ground to build tall valve well in order to reduce the project cost at the same time also can avoid the operation of the valve cause harm to the staff.
2 Directly buried fully welded ball valve is opened the valve ball seat completely surrounded despite impurities not scour seat and medium sphere seal face because of this special structure to make valve closure and pipes with the same life.
3 Closed buried type welded ball valve medium static damage on the sphere and the sealing seat open the sphere and the process of the stationary medium deposited debris scrape under seat spring compensation change of pressure and temperature compensation function ensure that won't produce any leaks.
