Do air valves cause electrical noise?

I have a system that appears to be affected electrically by an air valve that is operating a clutch. This problem wasn't always there, but it is now. It seems to be causing electrical noise which in turn is affecting one of the servos on the machine.

Could electrical noise start after a valve gets older? Am I looking in the wrong place? Thanks!

Are Lenze AC Tech drives reliable?

Does anyone have feedback on these drives. Not looking for a specific model from them, just a general consensus on whether they are worthy as a replacement drive.

The prices are good and that always scares me...
