Type R622 - Second-Stage regulators are Underwriters Laboratories (UL®) listed regulators designed to reduce the outlet pressure from a First-Stage regulator, usually 10 psi to 11 inches w.c., in domestic installations. Vents are screened with standard orientation over the inlet, but other orientations are available. Fisher® brand Second-Stage regulators are painted palm green for easy identification. Type R622 are equipped with a stainless steel inlet screen to reduce the amount of debris entering the regulator and have a temperature rating of -20 to 160°F, but have passed Fisher internal testing for lockup, relief start-to-discharge and reseal down to -40°F.
Type R622 - is designed for Two-Stage domestic applications up to 1,400,000 BTU per hour. 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 psi in an overpressure situation as required by NFPA 58. The relief valve design exceeds the industry standard by limiting the downstream pressure to 2 psi 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.
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 driplip vent design.
