The Science of Abrasion: How to Select Valves for Slurry Service

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.

Valve Selection Guide for the Paper and Pulp Industry: Fighting Clogging and Corrosion

The Paper and Pulp industry is one of the harshest environments for flow control equipment. The combination of abrasive wood fiber slurries, corrosive bleaching chemicals, and high-consistency pulp requires specialized valve designs. This guide focuses on the valves engineered to survive here: the Knife Edge Gate Valve for isolation and the Stainless Steel Butterfly Valve for utility, ensuring long-term operation without downtime from clogging or corrosion.
