These special purpose preset regulator are specially designed to deliver highly accurate consistent low pressure supply of nitrogen to oil filled power substation transformers. This new design consists of a two-stage preset regulator connected to a highly sensitive single-stage regulator that will deliver and maintain 0.50 PSIG in the head space within the transformer. A built in self relieving valve set at 8 PSIG protects the system from over-pressurization due to temperature variation. Both models come with bypass pressure valve allowing for rapid filling of the transformer at 6 PSIG of pressure. Regulator 16347-3 is constructed with an electrical switch that may be wired to an alarm or light to alert the operator when the cylinder pressure drops below 250 psig. For low pressure gas blanketing of oil filled sub-station power transformers.
