Why does my PRV whine or vibrate?
PRV chatter usually points to debris in the inlet strainer, unstable setpoint tuning, or internal seat wear. Start by cleaning the strainer and confirming downstream pressure with a gauge. If vibration persists after adjustment, the regulator may be near end of service life and need replacement.
