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 or R122H 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.
