Model Overview
The 770/772 is a double check assembly. It was produced from 1993-1997. The check bodies are made of ductile iron which is fused epoxy coated. The check is a stainless steel toggle linkage mechanism. The check springs are contained when the covers are removed. The spring tension must be released to repair the assembly. The bronze check seats are replaceable but a seat removal tool is needed for that purpose. Instead of a rubber disc a vulcanized clapper plate is used to seal the check. The shutoffs on the 772 utilized a special shutoff. The shutoffs used on the 772 are not standard. There are two different size flanges on the inlet and outlet.
