The CMO GL Slurry Knife Gate Valve has a monobloc reinforced cast iron body to ensure unobstructed flow and a watertight seal for complete fluid isolation. This valve doesn’t produce cavities when it’s open, eliminating turbulence in the fluid flow. A full port allows high flow rates with low pressure drop.
A push-through seat contains two opposing resilient rubber sleeves that seal against each other when the valve is open. Mounting this valve between two connection flanges compresses the sleeves which creates seal-tight isolation when the knife gate closes. No metal part of the valve comes into contact with the slurry. This design stops solids from building up, as there is no seat cavity which could prevent the gate from fully closing.
Available in wear-resistant natural or synthetic rubber, the sleeves enclose an integrally moulded metal ring that maintains the round shape and helps resist compression or stretching.
The CMO GL Slurry Knife Gate Valve is suitable for transporting highly abrasive media with up to 50% solids concentration.
