Food industry FAQs
You asked, we answered these common questions related to the food processing industry and rotary valves.
See all FAQs-
A.
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.

A.
Standard rotary valves can be time-consuming to maintain because they require tools to disassemble. Quick-cleaning models speed up the cleaning process by making it easy to access the valve’s internals. In the case of a Quick-Clean Valve with RotorRail, for example, you just need to turn a handle and slide out the rotor, which is set up on a rail system. It only takes a minute before you can start cleaning.
Relevant for: Conveying Systems, Reliability -
A.
In terms of options and accessories for the food processing industry, food-grade coatings and materials such as stainless-steel, Lectrofluor, and XTR-Coat are the best at preventing contamination. Rotors with U-shaped vanes reduce material packing and make cleaning easier. The valve itself must be properly welded and finished to ensure the surfaces are smooth and durable, which means there will be no cracks or crevasses for bacteria to build up.
