FEBCO 805Y-825/YD 8" CHECK SPRING

1 1/4 In To 2 In Rubber Plunger End Disc

Model Overview

The Model 805 is a double check assembly. It was produced from approximately 1979 to 1988. The body is of bronze construction and utilizes an in line check design. Check seats were cast into the body and were not replaceable. Check springs were contained when the cover was removed but the spring tension had to be released for proper repair. The 3/4"-1" internal hardware parts are mostly plastic. The 1 1/2"-4" internal hardware parts are mostly bronze. The 3/4"-2" size had check covers that screwed into the body.Febco model 825 is a reduced pressure backflow assembly. The model 825 was produced from approximately 1975 to 1988. The 1 1/2" and 2" sizes were discontinued in 1978 and the body was made of bronze. The 2 1/2"-10" check valve body was made of cast iron construction with a painted epoxy coating to inhibit rust. The first few years this valve was produced with some internal parts constructed out of aluminum causing premature and serious erosion. These parts were redesigned to avoid this problem. The check valves use the 805Y design of construction. The 2 1/2"-3" have an uncontained check spring. The 4"-10" have a contained check spring. Some versions of the contained spring check assembly required the spring tension to be released to change the rubber check discs. A spring removal tool is suggested to release the spring tension. Check seats were replaceable and a seat removal tool was needed to replace the seats. The 825D series was built from 1988-1989. The check valve utilizes the 805YD design of construction. The 2 1/2"-3" have uncontained check springs. The 4"-10" have a contained check spring design. The changes were that the body was made of ductile iron instead of cast iron and internal check parts are stainless steel instead of epoxy painted iron or bronze. The check bodies on 2 1/2"-10" were painted epoxy coated. In 1991 it was changed to a fused epoxy coating. The check seats are bronze and replaceable. In the 825D the check seats are bolted in and a special tool is not needed to replace the seat. The relief valve on both models was the same; it is a side mounted relief valve assembly that attaches by a special bushing to the body and can be removed from the check body. The relief valve utilizes an external relief valve sensing line. Most repair parts are the same for the 825 and the 825D models.
