2", 3", 4"
This is a double check assembly. It was produced from 1958 to 1975. This assembly cannot be repaired in line and must be removed from the piping for repairs. All sizes are of bronze body construction. The 2" size had two versions produced. The first was a screwed type body requiring the three piece bronze body to be screwed together. The second type was a flanged type body where the three bronze sections are bolted together. The 2" size has unions on both ends for removal and repairs. The 3" and 4" sizes are a two piece bronze body design in which the check assemblies screw into the body. The ends of both the 3" and 4" are flanged for removal and repairs. Check seats are not replaceable. Check springs are not contained on the 2" size when the body was split for repair. Most internal hardware parts are made of bronze. There was a version of the VC unit that utilized an SMR 714 air inlet head. This combination made this unit a two check pressure vacuum breaker. Repair parts for the checks were the same as in the VC series. For air inlet head repair parts see SMR 714.
