CLA VAL RP4 8" REPAIR KIT
Model Overview
This is a reduced pressure assembly. Production began in 1991. The 2" size was discontinued in 2003. The 2 1/2"-4" sizes were discontinued in 2005. The 6"-10" were discontinued in 2012. The RP4 was a redesign of the RP1-EX. Slight changes in design of the internal parts of the check and relief valve were implemented. The 2 1/2"-10" check bodies are cast iron with a fused epoxy coating. The 2" design is a bronze check body. The toggle lever check design used is the 3084. The workings of the 3084 are very similar to the 3081 check design as used in the RP1 series. Changes in the disc, disc retainer, and disc guide were implemented. Most internal check hardware parts are made of bronze. The relief valve used on the RP4 series is the CDHS 24. The CDHS 24 is similar to the CDHS 20 used in the RP1 series. The body is made of bronze. Changes in the stem, disc holder, and disc retainer were implemented. Most internal RV hardware parts are made of plastic. All seats are replaceable and check springs are not contained when the cover is removed. A seat removal tool is needed to change the check seats. This unit utilizes a single external relief valve sensing line. The relief valve spring is not contained when the relief valve body is disassembled. The relief valve can be removed from the check body and can be mounted on either side of the check body.
