Directly Buried Type Full Welded Ball Valve

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.
4, directly buried fully welded ball valve can be directly welded to save the flange, screw, gaskets, save a lot of material resources.
5, buried type full welded ball valve is better than that of butterfly valve, butterfly valve butterfly plate in the middle when the medium flow medium clutter can scour butterfly plate, the butterfly plate damage, the valve closes lax;
6, buried type full welded ball valve is superior to the gate, in addition to media clutter flush seal face, closed lax sealing surface damage.medium static medium sundry will hoarding in the valve gate slot gate close does not reach the designated position, to close the valve is lax.
