WATTS 990 6" #1 CHECK ASSEMBLY

Model Overview

The 990/992 is a reduced pressure assembly. It was produced from 1993-1997. The check bodies are made of ductile iron which is fused epoxy coated. The check is a toggle linkage mechanism. The check springs are contained when the cover is 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 relief valve body is of bronze construction and is attached to the check body by a threaded connection. The relief seat is replaceable and the relief spring is contained. An external relief valve sensing line is utilized. A special shut-off valve was utilized on the 992 series. The shut-offs on the 992 had flange dimensions different than a standard sized shut-off.
