Features
* 20Years Recommended Replacement Life
Fisher R622H is designed using rugged time proven design concepts
with enhancements to the corrosion resistance and durability of
materials both internally and externally. With proper installation
and periodic inspection and maintenance Fisher R622H design has a
20-Year Recommended Replacement Life. In some environmental
conditions earlier replacement may be required.
* lmproved Regulations
Fisher’s large molded fabric-reinforced diaphragm and spring
assistedvent stabilizer deliver accurate, stable regulation.
* Superior Overpressure Protection
The combination of a high capacity relief valve and largevent
provide overpressure protection which exceeds UL standards. When
used in conjunction with a Type R622 or R652 the two-stage system
will limitthe downstream pressure from the second-stage to2 psig
(0,14 bar) even in a double failure situation.

Fisher R600 Series second-stage regulators are Underwriters
Laboratories (UL) listed designed to reduce
the outlet pressure from a first-stage regulator, usually 10 psig /
0,69 bar to 11-inches w.c. / 27 mbar,
in domestic installations. Screened drip-lip vent has standard
orientation over the inlet with other orientations available.
Fisher second-stage regulators are painted palm green for easy
identification. Fisher second-stage R600 Series regulators
are equipped with stainless steel inlet screen to reduce the amount
of debris entering the regulator.Fisher Type R622 Regulator
is designed for Two-Stage domestic applications up to 1 400 000 BTU
per hour / 15,8 SCMH.
Fisher Type R622’s time proven design and corrosion resistant
materials, provide a recommended replacement life of 20 years.
Fisher Type R622 contains a high performance relief valve and a
large 3/4-inch screened vent to limit downstream pressure
to less than 2 psig / 0,14 bar in an overpressure situation as
required by NFPA 58.The relief valve design exceeds the
industry standard by limiting the downstream pressure to 2 psig /
0,14 bar even in a double failure situation when used
with a R622H First Stage Regulator.
Fisher Type R622 is adjustable from 9 to 20-inches w.c. / 22 to 50
mbar.
For easy system checks, Fisher Type R622 has 1/8-inch NPT built-in
gauge taps, orificed to a No. 54 drill size, on both
the upstream and downstream sides. Fisher R622 regulator also
features a large 3/4-inch drip-lip vent design.
