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.
