Knife Gate Valve Comparison

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

Welcome to our overview of the RHINOGATE™ Knife Gate Valve, a cutting-edge innovation in valve technology. Here, we compare RHINOGATE™ advanced design to traditional rubber “pop in sleeve” valves, highlighting its superior durability and efficiency. Our case studies showcase how RHINOGATE™ overcomes common valve failures, offering a leak-free, maintenance-friendly solution. Join us in exploring why RHINOGATE™ Knife Gate Valves are the top choice for industry experts.

CASE STUDY 1

Failure Due to Hardening of Sleeve Material.

When these types of valves remain in their closed position for extended periods – either in stock or installed in-line – heat and pressure can cause the valve’s rubber sleeves to lose their elastic memory and over time can lead to hardening of the sealing faces. This hardening hinders the sleeve’s ability to return to its intended sealing shape and typically results in a gap between the two rubber sleeve’s sealing faces causing a leak path.

RHINOGATE™ Advantage:

The RHINOGATE™ Knife Gate Valve incorporates a full bore design where all fluid media is contained within the one-piece liner.
As atmospheric leakage occurs – external atmospheric elements can cause the slurry to harden, resulting in a build-up of hard solid slurry which can jam the gate and prevent its closure.
RHINOGATE™ Knife Gate Valves are 100% leak free.
These types of valves typically have a drip tray or basin that requires constant maintenance. Constant seepage of slurry to the atmosphere during cycling is typical with these types of valves.
No drip tray or catch basins are required with the RHINOGATE™ Knife Gate Valve.

CASE STUDY 2

Failure Due to Gate Deformation.

Due to their split sleeve design, “pop in sleeve” style knife gate valves typically incorporate very thin gates. Pressure, heat, and water hammer can deform the gate over time. In abrasive applications, wear will also deteriorate the edges of the gate leaving it jagged, sharp, and bent.
When seating, due to its split sleeve design, deformation of the gate can lead to shearing and tearing of the rubber pop in sleeves – resulting in leakage to the atmosphere.

RHINOGATE™ Advantage

RHINOGATE™ Knife Gate Valves incorporate thick, robust gates – usually between 1.5 and 2 times thicker than “pop in sleeve” style knife gate valves. Extra added thickness prevents deformation from water hammer and pressure.
RHINOGATE™ Knife Gate Valves’ thick gates and full bore design eliminate any chance of shearing or tearing to its liner during seating.
