FAQs for Reliability

Q.
My rotary valve is stuck. What do I do?

A.
If your rotary valve is not rotating, it could be an issue with the power, the chain, the gearbox, or a foreign object stuck in the valve’s inlet.

If it’s stuck because of material buildup, there are a few different areas to look at: inspect the supply source and the piping of your conveying line. The issue could also be related to excessive pocket fill, moisture, or blowby air.

These are all specific issues, so check your maintenance manual for more in-depth troubleshooting tips.
Q.
What options can help sticky material flow better?

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.
Q.
I’m ordering a valve from the U.S. Do I need to worry about border delays or additional fees?

A.
Absolutely not! ACS is fully bonded, and we’re partnered with a company that picks up shipments daily. For you, that means no delays, customs duties or brokerage fees.
