HERSEY FRP 1 1/4-1 1/2" RUBBER KIT
Model Overview
This model is a reduced pressure assembly. Production was begun approximately in 1975 and was discontinued in 2004. You will notice there is a FRP & FRP II in the 3/4" and 1" sizes. The model FRP was the first introduction of this model and revisions were made which lead to the FRP II series and expansion of the sizes from 3/4"-2". The body is made of bronze. The check valve modules in both models are the same. The only difference in the FRP II is the shape of the relief valve component. The model FRP has a rectangular shape diaphragm with the relief valve section on the bottom pointing downward. The FRP II has a circular shape diaphragm pointing outward in line with the piping. All internal hardware parts are made mostly of glass filled noryl plastic. The checks are modular in construction. All seats are replaceable. A relief valve seat tool is needed to change the relief valve seat. All springs are contained when the covers are removed. The relief valve utilizes an internal sensing line.
