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.
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 299H – A high capacity pilot-operated regulator. Incorporates
a lightweight design (21 pounds / 10 kg) with dependable operation.
With a capacity up to 38,000 000 BTU per hour / 428 SCMH, the
Type 299H is ideal for applications from large commercial sites
to smaller multi-dwelling establishments. The unit comes with a
1-1/2 or 2-inch cast iron body with internal or external registration.
Internal registration allows easy installation while external registration
provides higher accuracy. 2-inch / DN 50 fl anged body or steel body
material also available. Alternate outlet settings from 3.5 inches w.c.
to 60 psig / 9 mbar to 4.1 bar are available. Temperature ratings for
the Type 299H is -20 to 150°F / -29 to 66°C. The Type 299H has
maximum inlet pressure rating of 150 psig / 10 bar so it cannot
be used as a First-Stage regulator.
Type 99L – Pilot-operated unit keeps outlet pressure constant despite
varying fl ow rates and inlet pressures. Designed to handle loads up
to 63,250,000 BTU per hour / 712 SCMH, the Type 99L is ideal for
multiple customer installations. The unique pilot design, with fast
opening and closing operation, makes the Type 99L ideal for large
industrial boiler applications. The Type 99L can be used for low
pressure. A downstream control line is required. Temperature ratings
for the Type 99 is -20 to 160°F / -29 to 82°C.
133 Series – Direct-operated Second-Stage regulator ideal for large
industrial applications with loads up to 70,875,000 BTU per hour /
798 SCMH. The unit can be used for either low pressure or
pounds service. Maximum inlet pressure is 60 psig / 4.1 bar and
a downstream control line is required. The 133 Series has a
temperature rating of -20 to 150°F / -29 to 66°C.
