RHINOGATE™ Slurry Isolation Knife Gate Valve Specifications.

Complete View Gate Valve

Specification Overview

Engineered with easy interchangeability in mind, the RHINOGATE™ knife gate valve consists of just 8 pieces and is extremely simple and easy to understand, operate, and maintain.

The one-piece liner, gate and gland are sandwiched between two split body halves of ductile iron and is totally leak-free and well-enclosed in a neat package.

Its superior quality, solid construction, and brilliant design, allow for the valve to be rebuilt on-site, for only around 15% of the cost of a new valve.

A RHINOGATE™ knife gate valve is considered an investment as the valve can go back into service, time and time again. The days of throw-away valves have come to an end.

Easily Field Repairable

One piece liner allows for quick and easy replacement.



One Piece, “Live Loaded” Packing

Easily replaceable packing offers zero leakage to the atmosphere and minimal maintenance.

Full Bore, Cavity Free, Bi-Directional Design

Full bore design eliminates turbulence and offers bi-directional versatility.

“U” Shaped Perimeter Sealing

“U” shaped perimeter seal design offers bubble tight shut off performance.

Rebuild the for approx 15% of the cost of a new valve

Liner and packing can be replaced over and over again easily and cost-effectively.

MSS-SP 81 Face to Face

Fully lugged flange faces and its MSS-SP 81 design ensure replacing your in-line valves is a simple operation.

The Heart of the RHINOGATE™

The heart of the RHINOGATE™ knife gate valve is its special once-piece, field-replaceable polyurethane liner.

With its full-bore design – fluid media is fully contained and does not come in contact with any other part of the body. Sealing of the gate is handled within the liner’s U-shaped perimeter core – offering bi-directional operation and complete bubble-tight downstream isolation.

Its cavity-free seat also eliminates pockets where slurry can build up and prevent the gate from closing. Built-in “Double V” scrapers assist in scraping the gate clean, each time it is cycled and outside seal rings eliminate the need for flange gaskets when installing the RHINOGATE™ in-line.
