Regulator Technologies 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 ori ce sizes, body sizes
and outlet pressure ranges are available. See the product guides on
pages 37 and 39. The Commercial Service (CS) Regulator Series
have a temperature rating of -20 to 160°F / -29 to 71°C, but have
passed Fisher
®
internal testing for lockup, relief start-to-discharge
and reseal down to -40°F / -40°C.
Note: Because of various spring ranges and orifi ce sizes, all
commercial and industrial regulators should be individually
sized for the particular installation. Consult specifi c product
bulletins for maximum pressures ratings. Contact your local
LP-Gas Equipment Distributor 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 / 88 SCMH, ideal for installations at schools, bakeries and
many other commercial/industrial applications. Available in 1-1/4,
1-1/2 and 2-inch body sizes with spring ranges from 4.5 inches w.c.
to 5.5 psig / 11 mbar to 0.38 bar.

1. Capacities are based on 10 psig / 0.69 bar and 2 inches w.c. / 5 mbar droop.
2. Capacities are based on 10 psig / 0.69 bar and 20% droop.
NOTE: Additional combinations of body sizes, spring ranges and ori ce sizes are available. See guides on page 37. Consult your LP-Gas Equipment distributor for more information.
Type CS200 – The Type CS200 is a medium capacity low-pressure,
direct-operated regulator designed for loads up to 3,800,000 BTU per
hour / 44 SCMH, ideal for installations on smaller commercial/industrial
applications. Available in 3/4, 1 and 1-1/4-inch body sizes with spring
ranges from 3.5-inches w.c. to 2 psig / 9 mbar to 0.14 bar.
Flanged Bodies – The Types CS400 and CS800 are available with
a fl anged body. Flanges are available in 2-inch / DN 50 body size and
CL125 FF end connection.
Type CS800 – The Type CS800 is a direct-operated, spring-loaded
regulator which has been engineered for low-pressure commercial
service applications. This regulator can accommodate up to 21,600,000
BTU per hour / 243 SCMH of fl ow capacity and is available in 1-1/2 and
2-inch body sizes with 8-inches w.c. to 5.5 psig / 20 mbar to 0.38 bar
pressure ranges.
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 fi xed piping
serving 14 inches w.c. / 35 mbar appliance systems require
additional overpressure protection to make the system compliant
with NFPA 58 requirements for a two-stage system. Please consult
with your LP-Gas Equipment Distributor for more information.
