1800C and 1800C-HC Series Service Regulators

Technical Bulletin

1800C and 1800C-HC Series Service Regulators 02 Elster American Meter

The 1800C Series pressure regulators are designed to control natural gas, air, nitrogen, carbon dioxide, propane vapor, and other non-corrosive gases in residential, light commercial, and small industrial applications.

General Information

Outlet pressures between 3.5" W.C. and 2 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).

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

• Widerangeofvalvebody connection sizes

Options

VentElbow

The regulator vent opening should face downward (6 o'clock) to minimize the chance of blockage from ice and snow. If not possible, a 3/4" NPT plastic, 90° vent elbow (part number 78041P025) and separate protective screen (part number 70400P017) may be screwed into the vent to provide the necessary protection.

ElevationCompensation

TheE.C.orificeisrecommendedfor

installations where the inlet pressure

mayvaryoverawiderange.TheE.C.

orifice is available in two sizes: 1/8" x 3/16" and 3/16". The capacities of these orifices are the same as the standard orifice of the same size.

Applications

Model Number Description

1813C Basic regulator with full-capacity internal relief with

1813C-HC Basic regulator with full-capacity internal relief with

1843C Basic regulator with full-capacity internal relief and

1843C-HC Basic regulator with full-capacity internal relief and

1853C w/ USSA Basic regulator with full-capacity internal relief and

1853C-HC w/ USSA Basic regulator with full-capacity internal relief and

splashes while providing a large external vent opening to keep regulators working properly.

SafetyShutoffDevices

Overpressure Shutoff (OPSO) — Operates independently. The OPSO will shut off the gas supply in the event of a serious downstream pressure build-up. These are available in two pressure ranges on the Models 1843C and 1843C-HC.

Spring Range Part Number

1 PSIG to 3 1/2 PSIG 71403P004

When the outlet pressure exceeds the OPSO set point, the pressure under the OPSO diaphragm (A) compresses the pressure spring (B) forcing the diaphragm

stem(E)upwardsandreleasingplunger (D).Thispermitstheshut-offspring(F)

to force the shut-off disc (G) against the back side of the special double-ended orifice.

Universal Safety Shutoff Assembly (USSA) — USSA protects the downstream piping from both over- and under-pressure conditions by shutting off the gas flow at the inlet side of the regulator orifice. Both Over- and under-pressure shut-off set points are adjustable depending on spring ranges selected.

Full-Open Regulator Relief Capacity

For sizing downstream relief valves, use the following formulas to determine the regulator full-open capacity:

Critical flow rates Sub-critical flows

P

Q = 0.5 C x Q = C x

Critical flow occurs when the absolute outlet pressure is less than about 1/2 of the absolute inlet pressure.

Q Maximum capacity of regulator

This is the maximum inlet the regulator should operate at to insure complete lockup at no-flow conditions.

Other Gas Capacities

To determine the capacity of these regulators for gases other than natural gas, multiply the values within the capacity tables by a Specific Gravity Conversion Factor (Fg). The table below lists this factor for some of the more common gases.

Gas Type Specific Gravity Conversion Factor (Fg)

Air 1.00 0.77

Butane 2.01 0.55

CarbonDioxide 1.52 0.63

Nitrogen 0.97 0.79

Propane 1.53 0.63

To calculate the Conversion Factor for other gases:

(Fg) =

Example:Ifusingpropaneandonlyhavingtablesbasedonnaturalgas, the Specific Gravity Conversion Factor is :

Regulator Pressure Rating

125 PSIG (8.6 bar) = Maximum recommended inlet pressure for normal service. Maximum recommended pressure may vary with orifice size.

175 PSIG (12 bar) = Maximum inlet pressure for abnormal or emergency service, without causing damage to regulator case.

2 PSIG (138 mbar) = Maximum outlet pressure for normal service.

10 PSIG (689 mbar) = 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 (3.5 bar) = Maximum outlet pressure for abnormal service without damage to internal components. If regulator is subjected to these conditions, it should be removed

from service.
