Fisher™ 912N Series Pressure Regulators

912N Series direct-operated, spring-loaded regulators are used in service and industrial applications. These regulators have limited-capacity internal relief across the diaphragm to help minimize overpressure. Any outlet pressure above the start-to-discharge point of the non-adjustable relief valve spring moves the diaphragm off the relief valve seat, allowing excess pressure to bleed vent. 912N Series regulators are built to provide accurate, sensitive control.
