Description

The Fisher R600 series second-stage regulators are designed to reduce the outlet pressure from a first-stage regulator in domestic applications. Inlet and outlet gauge taps allow for easy system testing. The combination of a high capacity relief valve and large vent provide overpressure protection that exceeds UL standards. When used in conjunction with an R122H or R622H, the two-stage system will limit the downstream pressure to 2 psig even in a double failure situation.

Fisher equipment must be installed, operated and maintained in accordance with Federal, state, and local codes and Fisher instructions. Only personnel trained in the proper procedures, codes, standards and regulations of the LP-gas industry should install and service this equipment.
