What is a Double Flange Knife Edge Gate Valve?

A Double Flange Knife Edge Gate Valve is an industrial isolation valve fitted with flanged connections on both ends, allowing it to be bolted directly into a pipeline for secure, leak-tight installation. It features a sharp knife-edge gate that cuts through slurry, pulp, and solid-laden media as it closes, ensuring reliable shut-off even with suspended solids present. Available in a wide range of body materials and sizes to suit varied industrial pipelines.

Anti-clogging gate design reduces maintenance and downtime
Wide material selection resists corrosion and abrasion
Multiple seat options allow chemical and temperature compatibility
Easy alignment and bolting simplifies installation

Working of Double Flange Knife Edge Gate Valve

The knife-edge gate moves vertically within the valve body to control flow. When open, the gate retracts fully, allowing unrestricted passage of slurry or solid-laden media. To close, the sharp gate lowers through the flow path, cutting through fibrous or settled solids as it descends, then seats firmly against the PTFE-sealed seat for a tight shut-off. The double flange ends keep the valve firmly secured to the pipeline, minimizing movement and ensuring consistent sealing over repeated cycles.
