V port ball valve
1.Brief Introduction:

  V port Segment ball valve is a quarter-turn control valve. V type valve core is designed with a special V shape notch. Segment ball valve is one type of ball valves, its closure is a half ball with V type port which has sharp edges. during operation the valve, friction action will be occurred between its closures that producing a strong shearing force to the medium, and a fan-shaped area will be formed between V type port of the ball and the port of seat ring, so the section are of flow port can be changed, and the medium can be precisely regulated. It is a kind of regulating valve with angel 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 systems in different industries.

 

2.Techincal parameters:

1.the V port disc assures smooth and accurate throttling actions on a wide range of applications,such as paper pulp with the pneumatic actuator and positioner,the valve can provides automatic control for flow,temperature,pressure

2.Blow-out Proof Stem

3.ISO Integral Mounting Flange

4.Anti-Static Construction

5.Fugitive Emission Control Device
