R600Series second-stage regulators are UL listed designed to reduce theoutlet pressure from a first-stage regulator in domesticinstallations. Type R622 is designed for Two-Stage domesticapplications up to 1 400 000 BTU per hour / 15,8 SCMH. Type R622contains a high performance relief valve and a large 3/4-inchscreened vent to limit downstream pressure to less than 2 psig /0,14 bar in an overpressure situation. Types R642 and R652 aredesigned in an angle body and back mounted design.
