CommerCial/industrial direCt-operated HigH-pressure regulators
For Commercial and Industrial high-pressure applications like
factories, of ce building, restaurants, etc., Regulator Technologies
has a wide variety of products. For ease of reference, only the most
popular commercial and industrial regulators are shown in these
pages. Other ori ce sizes, body sizes and outlet pressure ranges
are available. The higher capacities on commercial and industrial
installations usually require a Two-Stage regulator system.
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 pressure ratings. Contact your local
LP-Gas Equipment Distributor for assistance.
Types 627 and 630 – Large capacity direct-operated high-pressure
regulators designed for loads up to 10,700,000 and 14,000,000
BTU per hour / 120 and 157 SCMH, respectively. The Types 627
and 630 are normally used in conjunction with Type CS400 units,
however, they can also be used on Final-Stage (pounds-to-pounds)
service. Additional overpressure protection is recommended to
prevent excessive build-up in the downstream line. The diaphragm
case and body of the Type 627 can be rotated in four positions to
allow easy installation. Additional con gurations of the Type 627
with internal relief and control line connections for monitor systems
are available. For both the Types 627 and 630, additional pressure
ranges and ori ce sizes are available. Temperature ratings for the
Types 627 and 630 is -20 to 160°F / -29 to 71°C.
Note: Types 627 and 630 regulators do not have an internal
relief and should be installed with additional/external
overpressure protection. These units should not be installed
as part of a two-stage system in fi xed piping serving
14 inches w.c. / 35 mbar appliance systems unless additional
overpressure protection is installed that will make the system
compliant with NFPA 58 requirements for a two-stage system.
Please consult with your LP-Gas Equipment Distributor for
more information.
Flanged Bodies – The Types 630 and 627 are available with
fl anged bodies. Flanges are available for 2-inch CL300 FF.
Overpressure Protection – The Type 627 is also available in
monitor con gurations. Note that the Type 627 monitor regulators
have unique type numbers. For more information on monitor
overpressure protection, see page 42.
Fluorocarbon Trim – The Type 627 is available with
Fluorocarbon (FKM) Trim for high temperature applications such
as vaporizors. Part numbers are listed below with a ‘V’ suf x.
Temperature ratings for the Type 627 with FKM Trim is 0 to 180°F /
-18 to 82°C.
Type 1301F – The proven reliability and accurate regulation of the
Type 1301F regulator makes it ideal for numerous high-pressure
drop applications. This multi-purpose regulator can be used as pilot
supply or pressure-loading regulators where high-pressure operating
medium must be reduced for use by gas regulator pilots or pressure-
loaded regulators.
