Features and advantages

1 Full bore design
Meet the minimum bore requirements of API 6D and reduce flow resistance

·Easy for users to clean the pipeline through the ball

2 Two-way blocking and drainage

·The sewage in the middle cavity can be drained conveniently and safely with the sewage plug

·Online check for leakage at the valve seat seal when the ball valve is fully open or fully closed

Online replacement of valve stem packing or other seals

Customizable design configuration DBB, DIB-1 and DIB-2 structures

3 Automatic pressure relief function
When the pressure in the middle cavity of the ball valve is abnormally increased, the pressure in the middle cavity is automatically discharged to the flow channel

Ensure the safe use of ball valve
4 Anti-blowout and anti-static valve stem
·Anti-static structure is designed between the ball, valve stem and valve body

The valve stem is designed as an anti-blowout structure
5 Low torque switch design
The relative motion pairs of the ball valve are equipped with bearings with low friction coefficient

While ensuring strength, the switching torque is reduced, and the switch is reliable and light
6 Emergency compensation of seal (optional)
When the valve stem and valve seat leak due to damage, the sealing grease is injected through the grease injection valve for emergency sealing
