Description & Features

CV6600 hopper shape knife gate valve is used in service as a pneumatic residue discharge valve in pulp making, paper making and sewage treatment. This type of valve is well suited for high consistency media containing solids, fiber or residue, serving as a residue discharge valve on stock cleaners, gravity separators or pressurized screens. The "hopper" at the bottom of the valve collects waste discharged from the valve body during the closing stroke. This greatly reduces the wear between the body and gate, and prolongs the life cycle of the valve.


A sight glass set at the bottom of the hopper allows for observation of the waste level in the hopper.


Valve is full port in the open position with low flow resistance.


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.
