The Fisher Propane Regulator R232-BBF Specifications


A propane regulator manages the pressure inside your propane tank, which keeps the pressure from blowing out hoses or potentially causing an explosion either inside your tank or home. Fisher Regulators is a brand sold by Emerson Process Management, and this brand specializes in control equipment and regulators. Emerson Process Management is part of the Emerson company, which is headquartered in St. Louis, Missouri. One of its products is the Fisher Regulators’ R232-BBF propane regulator.


  • The R232-BBF propane regulator is part of Fisher Regulators’ Integral Twin Stage Regulators series. This series has a two-piece design, which means that it has both a first and second stage regulator. The First Stage Regulator has an outlet pressure of 10 pounds per square inch (PSI), and the Second Stage Regulator has between a 9- and 13-inch water column (WC) delivery pressure. This delivery pressure is contained within a single housing, and the housing connects to your appliance. To use this regulator, however, you must install your propane tank within 30 feet of the appliance.


  • All models of the R232 series feature a 90-degree vent opening, which means that you can install this regulator under your tank’s cylinder dome, and you can position your vent downwards. The diaphragm of this model has two pressure taps and a non-crimp bonnet assembly. It also features a flat inlet casing.


  • The outlet connection on the R232-BBF propane regulator is 1/2-inch female national pipe thread (FNPT), and the inlet connection is 1/4 FNPT. The regulator has a British Thermal Unit (BTU) capacity of 350,000 BTUs and features an internal relief feature. The vent is located over the outlet, and it uses a P100A bracket. The factory setting for this regulator is 11 WC.

Regulator Types

  • Fisher Regulators offers regulators for natural gas, propane, liquid, steam and specialty gases. The three main regulators offered by Fisher Regulators include relief/backpressure, pressure reducing and manifolds/changeover. The relief/backpressure keeps the correct upstream pressure by quickly responding to upstream pressure variations. The pressure-reducing regulators respond to the downstream pressure demand and release the correct amount of outlet pressure. The manifolds/changeover regulators are strictly for propane and natural gas systems and are for tank or multi-cylinder installations.
