Emerson™ has a wide range of low-pressure regulators to meet almost any commercial or industrial application. For ease of reference, only the most popular commercial and industrial regulators are shown on this page. Other orifice sizes, body sizes and outlet pressure ranges are available. See the product guides in the LP-31 catalog. The Commercial Service (CS) Regulator Series have a temperature rating of -20 to 160°F, but have passed Fisher™ internal testing for lockup, relief start-to-discharge and reseal down to -40°F.
Note: Because of various spring ranges and orifice sizes, all commercial and industrial regulators should be individually sized for the particular installation. Consult specific product bulletins for maximum pressures ratings. Contact your salesman for assistance.
Type CS400 – The Type CS400 is a medium capacity low-pressure, direct-operated regulator designed for loads up to 7,800,000 BTU per hour, ideal for installations at schools, bakeries and many other commercial/industrial applications. Available in 1-1/4, 1-1/2 and 2 in. body sizes with spring ranges from 4.5 in. w.c. to 5.5 psi.
Flanged Bodies – The Types CS400 and CS800 are available with a flanged body. Flanges are available in 2 in. body size and CL125 FF end connection.
Note: Types CS200, CS400 and CS800 regulators should be installed with additional/external overpressure protection. These units when installed as part of a two-stage system in fixed piping serving 14 in. w.c. appliance systems require additional overpressure protection to make the system compliant with NFPA 58 requirements for a two-stage system. Please consult with your salesman for more information.
