A custom modified version of the GL model, the CMO GLP Slurry Knife Gate Valve uses Abrasiguard sleeves. Abrasiguard is a proprietary polymer manufactured in Australia that improves seal reliability and overall service life. This upgrade makes the valve suitable for more challenging slurry applications.

The ported gate fully aligns with the resilient sleeves in the open position to form a full bore. This ensures unobstructed flow with high flow rates and low pressure drop. The polymer sleeves also compress on the gate through the entire stroke, flushing particles out of the bottom of the valve and creating a bubble-tight seal in the closed position. Because the sleeves completely supporting the gate, the GLP is better suited to non-vertical orientations than other types of knife gate valve.

The CMO GLP Slurry Knife Gate Valve is suitable for transporting highly abrasive slurry and is specified for horizontal installation.
