Type R642 - 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 R642 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 R642 - 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 13 inches w.c.
Types R642 and R652 are designed for domestic applications up to 920,000 & 1,000,000 BTU per hour, respectively. These units provide all the same features as the Type R622, including the 20-year recommended replacement life and double failure protection, in an angle body for the Type R642 and backmounted design for the Type R652.
