Emerson Fisher Type R130-21 1/4 in. FNPT Aluminum Changeover Manifold Assembly w/ 45 PSIG, 1.475M BTU/HR

Composed of two Type 67C regulators and a special 0 to 60psig/ 0 to 4.1 bar pressure gauge, the Type R130 delivers a 45 psig / 3.1 bar outlet pressure on supply and 30 psig / 2.1 bar on reserve. The gauge, which serves as the changeover indicator, is painted red from 0 to 35 psig / 0 to 2.4 bar range, it indicates that the manifold has switched from the supply to the reserve cylinder. The Type R130-21 has a temperature rating of -20 to 160°F / -29 to 71°C.

This product is backed by a 10 year warranty.

Note: These units are intended for use with Second Stage regulators and/or separate relief devices which provide overpressure protection required by NFPA 58. Capacity of all these changeover manifolds is dependent on the size of the Second-Stage regulator with which they are used. If the manifolds are used as a Final-Stage (pounds-to-pounds), a relief valve is required in the downstream system.
