R622 Second-Stage Fisher Gas pressure Regulators

 

Type R622 gas regulator 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, orificed 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.
