Fisher Controls R232-BBF LP-Gas Regulator

This Fisher Controls R232-BBF LP-gas regulator comes as seen in photos. The 1.7 ft copper pigtail line is designed to screw directly into a high-pressure propane cylinder/tank valve. This feeds gas into the Overpressure Shut-Off (OPSO) valve mechanism mounted on the left side of the regulator body. The low-pressure gas leaves the regulator on the right, passing by the pressure gauge (used to monitor system/appliance pressure) and flowing directly into the flexible 8.8 ft delivery hose that connects to an appliance.

The Fisher Controls R232-BBF is a highly efficient, high-capacity integral two-stage LP-gas regulator designed for domestic and light commercial propane systems. Engineered by Emerson-Fisher, this single-unit regulator combines a non-adjustable first-stage regulator and an adjustable second-stage regulator into one compact body. By dropping tank pressure down to a usable appliance pressure in a single piece of equipment, it drastically reduces installation footprint, piping joints, and labor costs.

Equipped with a large fabric-reinforced diaphragm and robust internal relief mechanisms, the R232-BBF ensures precise pressure regulation and maximum overpressure protection even in harsh winter conditions.
