Gland Advantage

The RHINOGATE™ Gland Advantage is a Huge Step Forward in Knife Gate Valve Technology.

Conventional knife gate valves have had an inherent problem with gland area leakage. Traditionally braided yarn or square-shaped seals are used in an attempt to create a seal between the gate and chest area of a knife gate valve – a difficult task to achieve. Premature failing of gland seals on knife gate valves is not an uncommon occurrence, often failing within the first 6 months of service. After years of design, testing, and trials – we here at RHINOGATE™ have found a solution to the age-old knife gate valve problem. Finally – a gland packing solution that will not leak nor require extreme amounts of maintenance.

One Piece Elastomer Gland Packing Guarantees No Leakage.

RHINOGATE™ knife gate valves use a specially engineered, one-piece, elastomer gland packing.

The gland packing is firm. It encompasses incredible sheer strength. Its texture is smooth and slippery. These are the traits of a material that has been purpose-designed for an extremely demanding application.

The one-piece elastomer gland packing is slid over the gate and pushed down into the chest area of the valve where it sits firmly onto the RHINOGATE™ liner. 

The gland follower is then slid over the gate and torqued down onto the gland packing – causing its deformation. It is this deformation that provides the long-lasting seal between the gate and the RHINOGATE™ liner preventing media discharge to the atmosphere.

  • No Leaks
  • No Mess, Spills or Clean Ups
  • No Multiple Pieces of Braided Yarns, Gaskets, Rings or Seals.

Live Loaded Belleville Washers Ensure Minimal Gland Maintenance Required.

RHINOGATE™ knife gate valves utilise special “live loaded” belleville washers to ensure even loading across our one-piece elastomer packing. Once torqued up our live loaded gland will not come loose, nor need repeated tightening like other conventional knife gate valves.

The gland follower is torqued down onto special belleville washers. Downward pressure provided by the cap screws is converted into a constant and live-loaded state. This constant state ensures pressure is evenly distributed across the one-piece elastomer gland packing and eliminates the need for consistent tightening of the gland follower.

  • Load Remains "Pre-Loaded" and "Live" at all Time
  • No Continuous Tightening Required
  • Minimal Maintenance Required Unlike Other Glands
