DeZURIK KLS Series Instrumentation Isolation Knife Gate Valve, 3-inch, 316 Stainless Steel, Part No. 9249645-003

The DeZURIK KLS Series Instrumentation Isolation Valve is a robust 3-inch knife gate valve designed for reliable isolation in demanding industrial applications, particularly in slurry, pulp, and paper, wastewater, and chemical processing environments. Constructed from CF8M (316 stainless steel) for excellent corrosion resistance, this valve features a unidirectional design with a resilient seat for tight shutoff and minimal leakage. The lever actuator provides manual operation with a position indicator scale for precise control, and it includes purge ports for cleaning and maintenance. Key benefits include high durability in abrasive media, easy maintenance with replaceable seats, and compatibility with high-pressure systems up to 150 psi. Compared to standard gate valves, the KLS offers superior performance in slurries due to its knife-edge gate that cuts through solids, reducing clogging. Drawbacks may include higher initial cost and the need for periodic seat replacement in highly abrasive conditions. This model, part number 9249645-003, appears used based on visible wear and labeling, with no attached sensors or controllers evident.
