Unidirectional Knife Gate Valve – Series 940, Lug Style Slurry Isolation Valve

The Series 940 Unidirectional Knife Gate Valve is purpose-built for one-directional shutoff of thick slurries, bulk materials, and media with high solids content. Featuring a lug-style body, it allows dead-end service and easy maintenance in demanding industrial settings.

Designed for industries such as mining, chemical processing, wastewater, and power, the Series 940 offers rugged performance with minimal maintenance. The gate is guided and supported to maintain tight shutoff, while the body is engineered for high structural integrity under pressure.
