Introduction to Pneumatic V-shaped Cut off Ball Valve: The pneumatic V-shaped cut-off ball valve manufactured by Yaosheng Company has a V-shaped notched ball core with a rotating shaft at the upper and lower ends of the core. This valve has a sturdy structure, wear-resistant valve material, a DC channel, and a seat with an energy increasing ring to adjust the sealing force. When closed, the V-shaped incision and valve seat generate wedge-shaped shear force, which is widely used in slurry, mud particles, and fiber environments. Pneumatic control and valve positioner are matched to achieve proportional adjustment, and a control box with a valve can quickly cut off.
