Unidirectional Knife Gate Valve – Series 942, Wafer Style for Slurry and Solid Media

The Series 942 Unidirectional Knife Gate Valve is designed for reliable, one-way shutoff in pipelines handling thick slurries, dry bulk solids, and abrasive fluids. Its wafer-style body allows for easy installation between flanges, making it a space-efficient option for retrofit and new systems. Engineered with rugged materials and reinforced gate support, this valve ensures tight sealing on the upstream side, making it suitable for applications in mining, power plants, cement, and wastewater processing.

The 942 series incorporates features such as replaceable wear components, multiple seat material choices, and actuator flexibility to enhance service life and process efficiency.
