DN25 V Notch Pneumatic Wafer Type Ball Valve

Wafer type segment ball valve ,V-Notch ball valve , pneumatic actuator segment ball valve

Coosai wafer type segment Ball valve combines the advantage of globe control valve with the eccficiency of a rotary ball valve which satsfify the needs for throttle and shut off of flow within automatic process industry.The segment ball in V-notch design has strong cutting force and self-cleaning function.With the segment ball quarter turning the passage area changesin ectorial shape.Leading to the precise control of the flowm,it is the ideal valve for most paper and pulp process application,Low CV value precise control is available by special V-notch on DN25 Segment ball.
