Your options are a shaft seal air purge kit, a rotor pocket air purge kit, or a combination of both. The answer is situational, but generally the shaft seal kit is best for abrasive materials, such as cement, or very fine materials that are prone to leaking. The rotor pocket option works well for ingredients that tend to pack or build up on your equipment. If your application presents a mix of both challenges, the combo air purge kit should come in handy.

It depends on the material, but the right valve can hold up well in abrasive applications. If you’re concerned about the valve’s lifespan and maintenance cycles, the proper configuration is key. That could mean coatings like hard chrome, heavy plate chrome, or tungsten; closed-end rotors made from stainless-steel or AR400 steel; or accessories like air purge kits.

Considering how many different types of rotary valves are out there, the important thing is to configure a rotary valve for your specific material and application. Things like proper valve sizing, pocket fill, and customization options contribute to the valve’s ability to keep materials intact. A valve expert can tell you more about what works best for your ingredients.

A.
Yes. If your facility generates combustible dusts, these safety features are non-negotiable (and unlike other vendors, ACS Valves does not charge extra for them). According to NFPA rules, a compliant rotary valve has metal tips on the rotor assembly, outboard bearings, and rotors with eight vanes or more. Some options will depend on your exact application, but a valve expert can guide you in the right direction.
