Description & Features

CV6200 double gate knife gate valve is typically used for on/off service in pulp making, slurry, residue discharge and sewage treatment. It is particularly suitable for residue discharge service on stock cleaners, gravity separators, hydrabrusher, .etc. in the paper making industry.


Double gate design shortens the full travel to half that of standard knife gates. The operation by twin cylinders will reduce the opening and closing speed by half.


Two-piece body construction with no cavities eliminates product build up.


Tight shutoff, stable performance.


O-ring loaded removable seat is self-compensating with good abrasion resistance and long service life.


Metal seat, PTFE seat, or EPDM seat available.
