Optional Third Stage Regulator
This preset regulator is specially designed to deliver a highly accurate and consistent low-pressure supply of nitrogen to oil-filled power transformers. Available with or without electronic pressure switch. 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.
