GAS PRESSURE REGULATOR

GENERAL INFORMATION

The American Meter 1213B pressure regulator is designed for natural gas
applications and features a compact, lightweight design for fast, easy
installation. Interchangeable orifices and springs provide a wide range of outlet
pressures and flow rates. Outlet pressures between 3.5" W.C. and 5 PSIG are
available. Operating temperature range is -20° F to 150° F (-30° C to 65° C).

The diaphragm case may be easily removed for routine inspection without
disturbing the line connections. All models conform to ANSI Code B31.8c-1994,
and CGA Service-type Regulator Specification CAN/CGA-6.18-M95.

Each 1213B regulator is equipped with a high tensile strength cast iron valve
body that rotates in 90-degree increments and features extra heavy wall
thickness. This provides maximum strength to withstand installation stresses
without damage and prevents thread galling experienced with aluminum.

1213B regulator valve bodies are treated with a 5-step metal finishing process.
The treated metal is then primed with an epoxy paint and finished with a tough
vinyl acrylic topcoat.

For available valve body sizes see table 1.

APPLICATION

The 1213B features a full capacity internal relief valve with large passages to
assure the fast release of gas. For added protection, a secondary relief valve
stop is provided to assure operation under the most severe conditions and in
the event the seal plug has been removed. The standard relief spring setting is

7.0" W.C. above the normal 7" W.C. outlet pressure. The relief point for a 2 psig

outlet spring is 1.6 psig above the outlet pressure.
Valve body configuration permits the 1213B regulator to be supplied in four

positions. All 1213B regulators are available with either right angle (90-degree)
or straight flow (180-degree) valve bodies. Vents can also be supplied in four
different positions.

The 1213B regulator is designed with an extra large, removable weather and
bug-proof stainless steel screened vent to resist freeze-ups and to exclude
foreign matter. The vent is threaded 3/4 inch NPT making it suitable for indoor
installations. The regulator vent opening should face downward to minimize the
chance of blockage from ice and snow. If not, a 90-degree vent elbow (Part
number 78041P025) and separate protective screen (Part number 70400P017)
may be screwed into the vent to provide the necessary protection.
