‘Fix me!’ 5 signs your valve needs attention

Find out how to diagnose and troubleshoot a rotary airlock valve that makes too much noise, stops rotating, or shows any of these other symptoms.

When my rotary valve jams, can I use tools to knock the material loose?

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.

I have products that are sensitive to shearing. Are there rotary valves designed to minimize product degradation during material transfer?

Factors like your material shape and size, equipment specifications, and conveying speed influence the right fill capacity to prevent jamming and shearing.

How are rotary valves manufactured?

How do I repair a rotary valve?

How to: Check rotor-to-housing tolerances

Keep your rotary airlock valve compliant with NFPA guidelines and maintain strong performance by checking your rotor-to-housing clearances regularly.
