Uniweld’s RV8012 is a heavy duty, single stage LPG (liquefied petroleum gas) and all fuel gas 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, 0-400 PSI Contents Gauge (Part No. G21) and 0-60 PSI Delivery Gauge (Part No. G25) allow you to monitor pressure flowing through the regulator. Additionally, as part of our RV80 series, the RV8012 comes with a removable back plug for fast seat servicing. The RV8012 has a CGA510 inlet connection, a “B” Left Hand 9/16 inch -18 Male outlet connection, with a delivery pressure of 2-40 PSI. 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.
