Knife Edge Gate Valves: 5 Design Features for Clog-Free Operation

Knife Edge Gate Valves: 5 Design Features for Clog-Free Operation

Blog /

Standard gate valves often fail in slurry and heavy-media applications because solids get trapped in the seat pocket, preventing a full close. Knife Edge Gate Valves solve this by design. Featuring a sharp, beveled blade that shears through media and a specialized flow path, these valves are the ultimate solution for paper pulp, wastewater, and thick slurry. Here are the 5 design features that ensure your flow control stays clog-free.

Slurry is a silent destroyer of industrial flow control systems. Whether it’s sand, ore, or paper pulp, the suspended solids act like sandpaper, scouring valve internals and forcing frequent, costly shutdowns. To survive, you cannot rely on “standard” valve specs. This guide dives into the science of erosion, the materials that provide a diamond-hard defense, and how to choose the right valve geometry—from Knife Edge Gate Valves to Pinch Valves—to keep your abrasive lines moving.
