The Fisher R130 changeover manifold assembly consists of two 67C series regulators and a special 0 to 60 psig (0 to 4.1 bar) pressure gauge. The gauge serves as the changeover indicator; it's painted red from 0 to 35 psig (0 to 2.4 bar) and when the dial reads in the red range it indicates that the manifold has switched from the supply to the reserve cylinder.
This unit is intended for use with second-stage regulators and/or separate relief devices which provide overpressure protection required by NFPA 58. Capacity of all changeover manifolds is dependent on the size of the second-stage regulator with which they are used. If the manifold is used as a final-stage (pounds-to-pounds), a relief valve is required in the downstream system.
