A.
Rotary airlock valves can be specified with features that support food safety and sanitation goals. We often recommend stainless-steel materials of construction, special coatings, and valves designed on a rail system for easy disassembly and cleaning.

A.
Rotary valves can be very effective at minimizing leakage when properly configured by an expert.
As a general recommendation to prevent dust leakage, valves should be equipped with ACST-4 shaft seals and an outboard bearing design. You should also check rotor-to-housing tolerances often, as enlarged tolerances can also cause leaks.

A.
Corrosive materials can damage the rotary valve’s internal parts over time, including the rotor-to-housing tolerances. We recommend a coating called XTR-Coat to minimize the effects of acidic, abrasive, or corrosive materials. Its durability prolongs the lifespan of your valve and parts, and its compliance with FDA and USDA regulations also makes it an excellent choice in many food-grade applications.

Whether you’re conveying ingredients for medicated pet foods, kibble with allergen control, or any pet food that must adhere to strict food safety guidelines, it’s important to prevent cross-contamination between batches. Make sure your valve is designed with outboard bearings and reliable shaft seals that are easy to replace.
To quickly wipe away residual product that may harbor bacteria, choose a Quick-Clean design, which allows you to open up the valve without tools for fast and easy cleaning. You might also consider sanitary materials and coatings, such as stainless-steel and XTR-Coat.
