Supapă cu bilă cu segment de flanșă, A216 WCB, DN200, PN16
Flange Segment Ball Valve is primarily designed for flow control, and it can also be used for shut-off operation. The notched port on the segment ball contributes to strong shear stress to cut through media with fibers and particles. Consequently, this v-port segment valve is a good general control valve for most pulp and paper process applications, or similar flow contains fibers and particles
flange 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.
