integral two-psi regulators
Integral Two-psi regulators combine a First-Stage regulator
and a Second-Stage, Two-psi regulator into one compact unit.
Recommended for installations where piping distance is short,
integral Two-Stage, Two-psi regulators provide all of the advantages
of Two-Stage regulation (refer to page 23). Fisher

Two-Stage, Two-psi regulators are color coded gray with a white cap
and white UV rated cover for easy identi cation. Vents are screened
with standard Second-Stage vent orientation over the outlet. The
Types R632E and R232E  rst-stage screened vent is threaded to
accept a 1/4-inch OD copper tube inverted fl are with a 7/16-24 UN
thread. The Types R23E and R632E have a temperature rating of
-20 to 160°F / -29 to 71°C, but have passed Fisher internal testing
for lockup, relief start-to-discharge and reseal down to -40°F / -40°C.
Type R632E – is an Underwriters Laboratories (UL
®
) listed regulator
with a capacity of up to 810,000 BTU per hour / 9.1 SCMH,
recommended for on-site cylinder installations, mobile homes and
domestic installations, where separation of the First and Second-
Stage is not cost effective. This unit offers a POL inlet connection for
the easy drop-in replacement of Single-Stage regulators.
Type R632E’s high capacity relief valve and large 3/4-inch screened
vent limit downstream pressure to less than 5 psig / 0.34 bar in
an overpressure situation as required by NFPA 58. Type R632E is
adjustable from 1 to 2.2 psig / 69 to 152 mbar, with a factory setpoint
of 11 inches w.c. / 27 mbar. The Type R632E features a 20-year
recommended replacement life.
Type R632E has 1/8-inch NPT built-in gauge taps ori ced to a
No. 54 drill size, on the upstream and downstream sides. These
taps provide easy access for testing the proper operation pressure
of the First and Second-Stage while the system is pressurized. This
regulator also features a large 3/4-inch drip-lip vent to reduce the
chance of blockage by freezing rain or sleet when properly installed
with the vent pointing down.
Type R232E – Designed for installations with small capacity loads
up to 450,000 BTU per hour / 5.1 SCMH. With an overall length
of 6.5 or 7 inches / 165 or 178 mm for NPT or FPOL connections
respectively, this compact unit  ts easily into con ned spaces
and is ideal for ASME tanks used on small domestic loads.
Intermediate and outlet gauge taps facilitate easy system testing.
A 3/8-inch NPT vent allows easy installation of vent piping. Use
of a valve stem and lever provide stable regulation and excellent
durability. A large fabric-reinforced diaphragm provides accurate
regulation. The large ori ce assists in minimizing freeze problems.
Stainless steel internal and corrosion resistant coatings provide
excellent corrosion resistance. The Type R232E also has the design
that provides a recommended replacement life of 20 years.
Twin Cylinder Installations – The Type R232E can also be used
on twin cylinder hook-ups found on travel trailers and stationary
applications. These units offer a drip-lip vent style for installations
without a vent protector. Proper installation requires the vent to be
pointed down in a vertical position. Additional protection may be
required if road splatter is a problem.
