V type ball valve

V type ball valve is one type of ball valves. Its closure is a half ball with V type port which has sharp edges. During operating the valve, friction action will be occurred between its closures that producing a strong shearing force to the medium, and fan-shaped area will be formed between V type of the ball and the port of the seat ring, so the section area of flow port can be changed, and the medium can be precisely regulated. It is a kind of regulating valve with angle rotation, having same sealing performance as common ball valves, so it simultaneously has both functions of regulating and on-off. Incorporating with pneumatic or electric actuators, it can be widely used in the automatic control system in different industries.
