Abstract
In a silently operating pilot-operated flow regulating valve, a main valve element is not allowed to vibrate freely, e.g., in lateral direction in an opened state and cannot constitute a noise source because while the main valve element is brought into its open position, an urging force acts upon the main valve element so as to tilt it into vibration suppressing contact with the valve seat whereby vibration of the main valve element is restricted.
