A.
Rotor-to-housing tolerances, or clearances, are the distance between your rotor tips and valve housing. Because they wear down over time, you should measure them as part of your regular maintenance routine. Increased tolerances leave a bigger gap for material to leak through, which prevents the valve from working effectively. This can lead to issues with material flow, NFPA compliance and safety, and overall efficiency. Check them often!
