Uniweld’s RV8013 is a heavy duty, single stage carbon dioxide regulator with a forged brass body and bonnet, and a 3-1/4 inch stainless steel diaphragm. A polished brass, single scale, 2-1/2 inch diameter, 0-3000 PSI Contents Gauge (Part No. G23) and 0-200 PSI Delivery Gauge (Part No. G24) allow you to monitor pressure flowing through the regulator. Additionally, as part of our RV80 series, the RV8013 comes with a removable back plug for fast seat servicing. The RV8013 has a CGA320 inlet connection, a Right Hand 5/8 inch Female outlet connection, and 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 single stage regulators are used for general purpose applications where nominal delivery pressure changes, due to decreasing cylinder pressure, do not affect operations. Single stage regulators have greater flow capacity than two stage models. Made in U.S.A.
