NATIONAL TOLL FREE DIRECTORY1-866-574-5100 | ON THE WEBwww.nee.ca REGULATORS DOMESTIC REGULATORS Integral Twin Stage Regulators An Integral Twin Stage Regulator is a two-piece design that combines a separate First Stage Regulator—(complete with an outlet pressure of 2 PSI) with a Second Stage Regulator, designed to provide 11” water column delivery pressure to the appliance all in one convenient housing. These are typically installed on a tank that is located within 30 feet of the appliance or load. This distance can be extended based on the BTU capacity of the application, but care must be taken with line sizing in order to ensure that the appliance inlet pressure requirements are met. Fisher Integral Twin Stage Regulators Features all the benefits of the 600 series in a single compact design; plus with improved flow capacity at cold temperature (-40ºF). The R232A Series is also available with a 90º vent option allowing the unit to be easily mounted under the dome of a cylinder with the vent pointed down. A larger molded diaphragm, dual pressure taps, wrench flat inlet casing, “non- crimped” bonnet assembly and re-designed seat and orifice design all contribute to a regulator with greater capacity and superior lock-up performance that’s easier for the serviceman to install. Fisher has introduced an industry first Twin-Stage compact 2-psig set point regulator (R232E Series ). Along with the improved Full Size series (R632E ), these upgraded Fisher regulator models offer the most diversified end connections in the market. The improved channel flow in the ‘E’ series through the inlet fitting allows for smoother flow and increased capacity. Both the R232E/R632E come complete with a UL-Listed UV protected label for clearer visual identification of the 2 PSI regulator and a white closing cap to further differentiate itself from the R232A Series.
