Regulator-2Nd 1/2X1/2Fpt 875K Btu 9-13Wc

FISHER™ R622-BCF Second Stage Regulator FISHER™ second-stage regulators are UL listed regulators designed to reduce the outlet pressure from a first-stage regulator, usually 10 PSI to 11 in. w.c./27 mbar. The vents are screened with standard orientation over the inlet, but other orientations are available. FISHER™ second-stage regulators are painted palm green for easy identification. Types R222, R622, R642 and R652 are equipped with a stainless-steel inlet screen to reduce debris from entering the regulator and have a temperature rating of -20 to 160°F. 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 in. 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 in. w.c. / 22 to 50 mbar. For easy system checks, the Type R622 has 1/8 in. 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 in. drip-lip vent design.
