The Series 19 modulating failsafe combines the features of a modulating unit with the reliability of a failsafe unit. With all of the same features of the modulating unit, the modulating failsafe employs a capacitor discharge design for the failsafe ability. When the power supply is lost, the failsafe system will cycle the valve to a predetermined position (open, closed, or as is).
