General Information

The American Meter Series CR4000 pressure regulator is designed for natural gas applications and features a compact, lightweight design for fast, easy installation. Interchangeable 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).

All models conform to ANSI Code B109.4-1998, and CGA Service-type Regulator Specification CAN/CGA-6.18-M95.

Application

The CR4000 features a full capacity internal relief valve with large passages to assure the fast release of gas (See performance graphs on page 3). The standard relief spring setting is 8.0" W.C. above preferred outlet pressure setpoint.

Regulator body configurations permit the CR4000 regulator to be supplied in 90° or 180° versions. The vent can be supplied in four different positions as shown on page 3.

The CR4000 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.

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 carrying components (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.
