Info
Type R622 is designed for Two-Stage domestic applications up
to 1 400 000 BTU per hour / 15,8 SCMH. The Type R622’s
time proven design and corrosion resistant materials, provide a
recommended replacement life of 20 years.
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 Type R622H or R122H First-Stage
regulator. The Type R622 is adjustable from 9 to 20-inches w.c.
/ 22 to 50 mbar.
For easy system checks, the Type R622 has 1/8-inch NPT built-in
gauge taps, orifi ced to a No. 54 drill size, on both the upstream and
downstream sides. This regulator also features a large 3/4-inch
drip-lip vent design.
