Overpressure Protection Options Integral Monitor PRIMARY REGULATOR Integral True-MonitorTM Protection Combines the operation of a conventional two-regulator wide-open monitor set into one device without the need for a downstream control line. Internal Relief Discharges gas across the diaphragm assembly to minimize overpressure. Slam-Shut Shuts off gas service to the downstream system in the event of an overpressure or underpressure condition.
