against downstream overpressure. Models 1853B2 and
1893B2 also include an underpressure shut-off (UPSO)
that provides protection in the event of an upstream failure.
Valve body configuration permits the 1800B2 Series regulators to be supplied in four positions as specified on page
7. All Series 1800B2 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.
All models are 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 or 1 inch NPT and is also available with BSPTR threads making it suitable for indoor installations.
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, 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- E.C. orifices are also available,
which provide constant outlet pressure even when inlet
pressure fluctuates greatly. The elevation compensation
orifice is a device which reduces changes in regulator
outlet pressure due to change in inlet pressure.
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" (Part number
73698G006) and 3/16" (Part number 73698G005). Its
capacity is the same as a standard orifice of the same size.

General Information
The American Meter Series 1800B2 pressure regulators are
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 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).
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 Servicetype Regulator Specification CAN/CGA-6.18-M95.
Exclusive, 7 - Step Corrosion
Protection
The protective finish on the Series 1800B2 regulators
resists corrosive effects of weather and harsh environments better than any other in the industry. Each precision
die cast aluminum regulator is treated-inside and out-with a
special conversion coating that's part of an exclusive, 7step finishing process.This coating greatly inhibits oxidation
of the metal's surface that can eventually compromise the
integrity of the metal. It also prevents finish paint from
cracking and blistering.
A single coat polyester primer and the high solid
polyurethane top coat provides a long-lasting protection to
all exterior regulator surfaces.The American Meter conversion coating process meets all environmental protection
regulations.
High Tensile Strength Valve Bodies
Each Series of 1800B2 regulator is equipped with a high
tensile strength cast iron valve body that rotates in 90degree increments and features extr a hea vy w all thic kness.
This provides maximum strength to withstand installation
stresses without damage and prevents thread galling
experienced with aluminum.
Series 1800B2 regulator valve bodies are treated with a 5step metal finishing process. The treated metal is painted
with a single coat polyester paint.
Available valve body sizes are: 3/4" x 3/4", 3/4" x 1",
3/4" x 1-1/4", 1" x 1", 1" x 1-1/4" and 1-1/4" x 1-1/4" NPT or
BSP-TR. Also available is a offset valve body in 3/4" x
3/4", 3/4" x 1" and 1" x 1" NPT or BSP-TR.
Application
Models 1813B2, 1833B2, 1843B2 and 1853B2 features a
full capacity internal relief valve with large passages to
assure the fast release of gas (See performance graphs on
page 6). For added protection, a relief valve stop is provided to assure operation under the most severe conditions.
The standard relief spring setting is 8.0" W.C. above the
normal 7" W.C. outlet pressure.
Models 1843B2, 1853B2, 1883B2 & 1893B2 are equipped
with overpressure shut-off (OPSO) that provides protection

General Information
Ideal for light commercial and industrial use, the 1-1/4"
1800B2-HC Series regulator is designed to increase output
capacity and lessen compounding during medium- to highinlet pressure operations. Compounding usually occurs
when a larger valve body introduces undesirable flow
characteristics, thereby creating an inefficient, boosting
effect in the outlet port of the body.
The 1800B2-HC regulator’s lightweight design features
high-capacity capabilities for 1-1/4" NPT connections and
flow capacities up to 4600 SCFH depending on inlet
pressure and orifice selection. It complements the 1800B2
Series family of regulators.
A lightweight regulator designed to increase capacity output and minimize the outlet boosting effect that is typical
from a larger valve body.
All models conform to ANSI Code B109.4-1998 and CGA
Service-type Regulator Specification CAN/CGA-6.18-M95.
