Emerson Fisher 67CD Series 1/2 in. FNPT High-Pressure Regulator w/ Dial Cap Adjustment 50 PSI, 1.5M BTU/HR

Description

Fisher automatic changeover regulators change from the supply cylinder (when gas is exhausted) to the reserve cylinder automatically. Type 749B is a large capacity changeover manifold for commercial and industrial applications. It consists of two 64 Series regulators and a Type 803 direct indicator. The assembly is used primarily in conjunction with either a Type HSRL or 64SR regulator.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. Specifications Capacity: 1,500,000 BTU/hr (11.3 SCMH) Inlet Connection: 1/2 in.
