Description & Features

CV4200 Pneumatic Segmented V Ball Valve
CV4200 Segmented V Ball Valve  Segmented Ball


CV4200 is a V ball segmented valve with metal to metal or metal to PTFE sealing and mostly used as a control valve. V-notch ball creates excellent shutoff and shearing by ball and seal, it’s suitable to control of fiber and slurry fluids service, widely applicable as power plant, chemical, paper making and light industry, .etc.


Compact construction, light weight and small volume.


One piece, leak proof valve body.


Splined shaft extra strength with no lost motion or dead band.


Straight through flow, high capacity, stable throttling.


Excellent shearing action in fibrous fluid mediums and generous clearance.


Superior trunnion bearing sintering treatment for excellent abrasion resistance and self-lubricating to eliminate galling.


Spring loaded seat for excellent sealing capacity.


Full area and reduced capacity in all sizes.


Low operating torque, accurate control.


High quality and low life cycle cost, easy disassembled seats.
