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 sqaure 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 un-common orrcurence, often failing within the first 6 months of
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.
The search is over™.
THE RHINOGATE ONE PIECE ELASTOMER GLAND PACKING GUARENTEES NO LEAKAGE.
Rhinogate knife gate valves use a specially engineered, one piece, elastomer gland packing.
The gland packing is firm. It encompasses incredible shear strenth. It's texture is smooth and slippery. These are the traits of a material that has been purpose designed for an application that is extremely demanding.
The one piece elastomer gland packing is slid over the gate and pushed down into the chest area of the valve where it seats 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 MULTIPLE PIECES OF BRAIDED YARN, GASKETS, O-RINGS OR SEALS.
NO MESS, SPILLS OR CLEAN UPS.
LIVE LOADED BELLEVILLE WASHERS ENSURE MINIMAL GLAND MAINTENACE REQUIRED.
Rhinogate knife gate valves utilize 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
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 consistant tighening of the gland follower.
