Knife gate valves are purpose-built for handling media with suspended solids, slurries, and viscous fluids. Featuring a gate that cuts through thick, abrasive material, these valves deliver reliable shut-off in challenging flow conditions.
Their simple, open-body design allows for minimal pressure drop and full-bore flow when open, making them ideal for isolation applications in demanding industrial processes.
Knife gate valves are available in both unidirectional and bidirectional designs. Unidirectional models are optimized for flow in a single direction, using resilient or metal seats to achieve a seal. Bidirectional versions enhance system flexibility by accommodating flow in either direction and are often equipped with robust gate supports to minimize deflection under pressure.
Material selection, including stainless, duplex, or specialty alloys for the body and gate, and elastomers or PTFE for the seals, is tailored to resist corrosion, abrasion, and chemical attack based on the application's specific requirements.
Industries like oil sands, mining, wastewater treatment, and pulp & paper rely on knife gate valves for their ability to isolate thick, solids-laden fluids where other valves would fail or plug.
Their rugged construction, ease of maintenance, and dependable shut-off performance make them a go-to solution for systems exposed to heavy wear, harsh chemicals, and high solids content.
