Outboard bearings are mounted on the outside of a rotary valve’s housing, while inboard bearings sit on the inside of the endplates. Because they’re located closer to the seal, inboard bearings are typically associated with more frequent repairs and a greater risk of contamination. Outboard bearings leave a gap between the seal and bearings, which makes them safer and more reliable in the long run.

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.
