Ground Breaking Knife Gate Valve Technology.

Traditional valves often suffer from gland area leakage, a challenge that conventional braided yarn or square-shaped seals struggle to overcome, typically failing within the first six months.

Rhinogate has innovatively addressed this long-standing issue. Our one-piece elastomer gland packing ensures a leak-free, low-maintenance solution, ending the search for a reliable seal.

This specially engineered packing offers exceptional shear strength and a smooth texture, perfectly designed for demanding applications.

Patented Innovated Knife Gate Design

The RHINOGATE™ Patented Collapsible Seat, is a unique innovation in the world of slurry isolation knife gate valves.

This groundbreaking design features bi-directional functionality and full bore operation, without any pockets or grooves where solids could accumulate, a feature exclusive to RHINOGATE™.

The polyurethane seat, upon gate closure, aligns perfectly with a specially crafted cavity ring, ensuring a 100% leak-proof seal and preventing gate deflection.

When the gate retracts, the seat seamlessly returns to its original position, maintaining full bore functionality and a smooth, groove-free seat area.
