This was a reduced pressure assembly. It was produced from 1970 to 1988. The 3/4"-4" was a bronze bodied unit with an in-line check design. The 3/4"-2" size had to be removed from the piping for repair. All seats were replaceable on all sizes. The first check and relief valve springs were not contained when the assembly was disassembled. Special tools were suggested to perform a repair on this model. The 4" and 6" size body were made of cast iron and also had the in-line check design. The 4" was available in either bronze or cast iron body. The cast iron versions 4"-6" were either painted epoxy coated or galvanized to minimize rust. Special tools were needed to disassemble and repair this model.
