Description

This is a reduced pressure assembly. The Beeco Model 6C was produced from approximately 1965 to 1978. Sizes 1"-4" are all bronze body construction. In the1"-4" size the check seats were cast into the body and are not replaceable. The 6" size was produced in both bronze body and galvanized cast iron body. Be sure to specify which you have because repair kits are not interchangeable. The 6" cast iron unit had replaceable check seats, the 6" bronze did not. The 8" and 10" body are constructed of galvanized cast iron and had replaceable check seats. All sizes 1"-10" had replaceable R.V. seats. There is a hot water (140°-210° F) repair kit available for sizes 1"-4". On the 1"-2" size some check covers were screwed onto the body and some were bolted. The internal hardware was made mostly of bronze. The first check spring was contained on the 1 1/2"-10" size when the first check cover was removed. The second check on the 2 1/2", 6", 8", and 10" had a contained spring design when the cover was removed. The R.V. spring on all sizes was contained when the cover was removed. The relief spring tension had to be released for proper repair. The relief valve had an internal sensing line. The relief valve required a very precise adjustment of the relief valve seats. Read the repair section to understand this important adjustment procedure.
