Airgas - MIL16391 - Miller? Low Pressure 3 Stage Nitrogen Three Stage Regulator

Miller? Three-Stage Nitrogen Blanketing Regulator, .5 PSIG - This preset three-stage regulator is specially designed to deliver a highly accurate and consistent low-pressure supply of nitrogen to oil-filled power transformers. The regulator will deliver and maintain 0.50 PSIG in the head space of oil-filled transformers. A built-in self-relieving valve set at 8 PSIG protects the system from over-pressurization due to temperature variation. Both models come with rapid-fill bypass pressure valve allowing rapid filling of the transformer with 6 PSIG of pressure.
