The 1800CPB2 is a compact, lightweight design for gas distribution systems as intermediate or low- pressure regulators. It will control outlet pressures between 1 to 30 PSIG (70mbar to 2 bar) within ±1% of the absolute set pressure over a wide range of flow rates. Temperature range -20°F to +150°F (-30°C to 65°C). Body variants 90 Degree - 1800CPB2 only (Right Angle), 180 Degree- 1800CPB2 and 1883CPB2 with OPSS (Straight-Flow).
