Uniweld’s RHT8015 is a medium / heavy duty, two stage nitrogen regulator with a machined brass body and chrome plated bonnet. The RHT8015 contains two tri-layered reinforced neoprene diaphragms with the first stage at 1-5/8 inches and the second stage at 2 inches. A gold painted steel, single scale, 2 inch diameter, 0-4000 PSI Content Gauge (Part No. G7S) and 0-200 PSI Delivery Gauge (Part No. G4S) allow you to monitor pressure flowing through the regulator. The RHT8015 has a CGA580 inlet connection, a Right Hand 5/8 inch -18 Female outlet connection, with a delivery pressure of 5-125 PSI. The regulator also includes an externally serviceable pressure relief device (PRD) which protects the regulator. The PRD is not designed to protect the downstream equipment. Uniweld two stage regulators are used where steady delivery pressure is required over a range of decreasing cylinder inlet pressure. Delivery pressure will remain constant until inlet pressure is nearly depleted. Made in U.S.A.
