While they have slightly different characteristics, sugar and salt both tend to do well with a 304 stainless-steel rotor and a food-grade, anti-corrosive coating called XTR-Coat for the housing. The coating provides a durable, non-stick surface to extend the valve’s lifespan and maintain consistent material flow.

Material buildup and flow issues like bridging can happen when plastic resins flow through the system too quickly, or when your equipment lacks the proper accessories to handle flow issues. Ensure rotary valves are properly sized for your material, system, and desired rate of flow, and consider accessories such as shear protectors and air purge kits to prevent issues such as shearing, jamming, and buildup.
