Food industry FAQs
You asked, we answered these common questions related to the food processing industry and rotary valves.
See all FAQs-
A.
While we understand the temptation for a quick fix, we definitely don’t recommend hitting your valve with hammers, wrenches, or whatever tools you have on hand. It only damages the valve and doesn’t help with material blockage. If you need help improving material flow, speak to one of our valve experts for recommendations specific to your application.
Relevant for: Technical Support, Difficult Products -
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.
Relevant for: Difficult Products, Safety -
A.
We have lots, and they depend on your application. One approach is coatings, like hard chrome or the abrasion resistant XTR-Coat, which can help material slide through the valve without sticking.
Before we make this answer too complicated, check out our blog on material flow tips.

A.
Rotary valves built on a rail system are specifically designed for faster cleaning, because you don’t need tools or a lot of effort to open up the valve and access the internal housing. The ACS Valves model is called the Quick-Clean, and it’s designed to help you clean up in just a few minutes. You could also add a U-shaped rotor, which has round pockets to prevent stubborn material buildup.
