Product overview
Structural characteristics
1, with excellent adjustment characteristics: pneumatic V-shaped ball valve has an approximate equal percentage of natural flow characteristics and up to 300:1 adjustable ratio. Pneumatic V-valves therefore provide precise control over a wide range of variations.
2, the opening and closing parts adopt V-shaped spherical structure, which solves the problem that the valve cavity is easy to deposit medium.
3, pneumatic V-shaped ball valve adopts double bearing structure, high mechanical stability, small starting torque, to ensure that the valve has a good sensitivity and induction speed.
4, high reliability (safety) : the valve body is a whole, durable, operation is not affected by pipeline pressure, and can avoid valve body leakage.
5, superior sealing of metal seat: Pneumatic V-shaped ball valve adopts movable metal seat, self-compensation function, and has superior sealing performance and long service life.
