What makes the “scrunching and grinding” sound when I turn the handle of my manual valve?
Most likely a corroded thrust bearing is causing the noise. The bearing is located on the valve shaft and is normally well lubricated. If the valve has been mounted with the stator facing up, solvents leaking onto the valve could have leaked down the stator screws and into the thrust bearing. The thrust bearing can be easily replaced.
