 General Information
|
|
| |
The American Meter Series 1213B2 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). Maximum flow rate is 2500 SCFH ( 70.8 m3 /h).
The diaphragm case may be easily removed for routine inspection without disturbing the line connections. All models conform to ANSI Code B109.4-1998, and CGA Service-type Regulator Specification CAN/CGA-6.18-M95.

Features |
|
| |
In response to a market survey, the following features were designed into the 1213B2 regulator to accommodate the customers needs. |
|
| |
- Improved relief performance.
- Improved performance repeatability.
- Lever design provides for secondary emergency relief in the event of unauthorized removal of the seal plug.
- Snap-in internal components (quick change outs).
- Non-adjustable relief.
- Larger seat disc area.
- 1213B and 1213B2 use the same seal plug to avoid loss of emergency relief should the seal plugs be interchanged.

Application |
|
| |
The 1213B2 features a full capacity internal relief valve with large passages to assure the fast release of gas (See performance graphs on page 5). 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 8.0" W.C. above the normal 7" W.C. outlet pressure.
Valve body configuration permits the 1213B2 regulator to be supplied in four positions as specified on page 7. All 1213B2 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 1213B2 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.

Pressure Rating |
|
| |
125 PSIG = Maximum recommended inlet pressure for normal service.
Maximum recommended pressure may vary with orifice size.
175 PSIG = Maximum inlet pressure for abnormal or emergency service, without causing damage to regulator case.
5 PSIG = Maximum outlet pressure for normal service.
10 PSIG = Maximum outlet pressure which can be contained by pressure carryingcomponents (no flange leakage to atmosphere except for normal relief action).
If regulator is subjected to these conditions, it should be removed from service.
50 PSIG = Maximum outlet pressure for abnormal service without damage to internal components.
If regulator is subjected to these conditions, it should be removed from service.
