Pneumatic V-type ball valve features
 1, compact structure, small size, can be installed vertically and so on. 
 2, with excellent regulation features: V-type ball valve has an approximate equal percentage of the inherent flow characteristics and up to 300: 1 adjustable 1, compact, small size, can be installed vertically and so on. 
 2, with excellent regulation features: V-type ball valve has an approximate equal percentage of the inherent flow characteristics and up to 300: 1 adjustable ratio. V-valves therefore provide precise control over a wide range of variations. 
 3, the maximum flow volume: Due to its streamlined shape and full right-angle rotary control, so that the maximum volume is particularly high, particularly large flow capacity, flow resistance is small, so you can use smaller and more economical and practical valve size. 
 4, V-type ball valve with double bearing structure, high mechanical stability, low starting torque to ensure that the valve has excellent sensitivity and sensing speed. 
 5, the most reliable (safety): the valve body as a whole, durable, the operation from the pipeline pressure, and to avoid valve leakage. 
 6, the superior sealing of the metal seat: V-type ball valve with movable metal seat, self-compensation function, and has superior sealing performance and long service life. In the flow direction, the amount of leakage ≤ 10-6 × rated flow coefficient. 
 7, super shear capacity: V-type ball valve with a metal seal structure, V-shaped ball valve seat and the metal valve seat during the rotation, V-notch and the valve seat to produce a strong shear force to cut off impurities such as fiber , And has a self-cleaning function to prevent the valve stuck phenomenon.
