Pneumatic V-port control ball valve

Overview of Pneumatic V-port control ball valve

Pneumatic V-port control ball valve starts cylinder spring preloading and movable metal valve seat structure with compensation. The ball core and the control unit seat will not be blocked or separated. The V-shaped notch on the ball core and the metal valve seat have shear effect and are suitable for controlling high viscosity media, including fibers, solid particles and slurry. The development of pulp with paper industry structure has advantages. The valve has large flow and small pressure loss, and the medium will not be transferred in the valve body cavity. The valve has approximately equal proportional flow characteristics and a large adjustment range.

Features of Pneumatic V-port control ball valve

1. The utility model has the advantages of compact structure, small volume, horizontal installation and so on.

2. This includes excellent regulation characteristics: V-ball units have approximately the same percentage of natural flow characteristics and have excellent adjustable ratios up to 290 SYm

3. Large volume: it is planned to adopt streamlined form, full right-angle rotation control, with large actual volume and small proportion. Therefore, more compact and economical valve shapes and sizes can be used.

4. V-ball valve adopts double bearing structure, high mechanical stability, small starting torque, to ensure that the valve has excellent sensitivity and induction speed.

5. High reliability (high safety): the whole valve body is strong and durable, operation is not affected by pipeline pressure, can avoid valve leakage.

6. Metal seat sealing performance is superior: V-ball valve adopts movable metal seat, with self-compensation function, superior sealing performance and long service life



Note: Any special design or question of  Pneumatic V-port control ball valve, kindly contact the manufacturer for more details.
