Unidirectional Knife Gate Valve – Series 950, Heavy-Duty Slurry Isolation Valve

The Series 950 Unidirectional Knife Gate Valve is engineered for demanding slurry, pulp, or bulk material isolation applications where dependable one-way flow control is essential. Its heavy-duty body and gate materials allow for long service life in abrasive and corrosive conditions, while the precision-machined gate and resilient seat deliver tight shutoff in the flow direction.

This valve is ideal for industrial processes such as mining, pulp & paper, wastewater treatment, and chemical processing where unidirectional flow isolation is preferred. Available in a variety of sizes, materials, and actuation types, the Series 950 is a rugged and reliable solution for isolation of thick, particulate-laden fluids.
