Uniweld’s R1563 Nitrogen Regulator is a single stage specialty regulator that comes in a machined brass body, polished chrome bonnet, easy to read, single scale, 1.5 inch gauges, and protective rubber gauge boots. Regulator has a CGA580 inlet connection, 1/4” Male SAE Flare outlet connection, with a delivery pressure of 5-175 PSI. Product also includes an externally serviceable pressure relief device (PRD) which protects the regulator. The PRD is not designed to protect downstream equipment. Uniweld single stage regulators are used for general purpose applications where nominal delivery pressure changes, due to decreasing cylinder pressure, will not affect operations. Single stage regulators have greater flow capacity than two stage models.
