Straight Through Buried Welding Ball Valve (Short Shape)
Direct buried full welding ball valve product profile:
The direct-buried all-welded ball valve is welded by forging and pressing the plate. The weight is about 10~20% lighter than the bolted structure, and the valve volume is smaller. It also reduces the leakage point of the valve and improves the reliability of the valve. Different driving modes can meet the control requirements of different industries and mines. For the buried condition of the valve, the design of the valve extension rod, maintenance of long pipe and control valve, so that the directly buried extension rod can be controlled on the ground welding ball valve, the surface of the valve spraying epoxy resin, field pipeline bonding and cathodic protection measures, adapt to the buried environment.

Directly buried all-welded ball valve structure features:
1, directly buried fully welded ball valve can be directly buried in the ground, without the need to build a tall valve well, in order to reduce the cost of the project, at the same time can also avoid the operation of the valve caused by personnel injury.
2. When the direct-buried full-welded ball valve is opened, the valve ball is completely surrounded by the seat, although the medium has impurities, the valve seat and the ball sealing surface can not be scour. Because of this special structure, the valve sealing property and the pipeline have the same life.
3, closed directly buried ball valve medium static damage to the ball and seal seat, open the process of the ball and the media is still deposited debris scraped off, the valve seat under the spring compensation for pressure and temperature changes have a compensation effect, to ensure that there will not be any leakage.
4, directly buried fully welded ball valve can be directly welded to the pipeline to save flange, screw, gasket, save a lot of material resources.
5. Valve stem flight-proof structure: set a step at the lower part of the valve stem and install the valve stem from the inside of the valve body to prevent it from flying out.
6, according to the pipeline construction and design requirements, adjust the length of the valve body and the height of the stem.
