THE RHINOGATE PATENTED* COLLAPSIBLE SEAT IS A UNIQUE DESIGN
The Rhinogate slurry isolation knife gate valve encompasses a revolutionary, patented collapsible seat design.
This design offers bi-directional versatility, full bore operation and encompasses no pockets or grooves in the seat area where solids can cake up and prevent gate closure - a feature which is unique only to the Rhinogate. During gate closure the polyurethane seat is forced into the specially designed cavity ring. The groove in the cavity ring locks in the gate, preventing gate deflection and ensures a 100% leak proof seal. Upon gate retraction, the polyurethane seat returns to its original position, there-by allowing full bore operation – and no pockets or grooves in the seat area.
