    805Y

    Febco 805Y and 805YB are double check assemblies. The 3/4"-2" 805Y was discontinued in 2003. The 3/4"-2" size 805Y has bronze body construction with plastic poppet type check design. The check covers screw into the body. Check springs are not contained. Before 1994 the check seats were not replaceable. In 1994 the 3/4"-1" had replaceable check seats available as an option. The replaceable check seat version is known as the model 805YR. A seat removal tool is needed to change the bronze seats. In 1995 the model 805YB was introduced to be used as a bypass assembly in certain models of Febco double check detector assemblies.

    805YD

    Production of the 2 1/2"-10" 805Y series ended in 1988. The 2 1/2"-10" 805Y is a painted epoxy coated cast iron check valve body. The internal check hardware on the 2 1/2"-3" was made of bronze while the 4"-10" was epoxy coated iron. The check seats are replaceable on the 2 1/2"-10" 805Y. A seat removal tool was needed to replace the seats. The 2 1/2"-3" have springs that are not contained. The 4"-10" size has contained springs. Some versions of the 4"-10" had to release the spring tension in order to change the rubber check discs. A spring removal tool is necessary to release spring tension. The first few years the 805Y was produced with some internal parts constructed out of aluminum causing premature decomposition. They were later redesigned to correct the problem. The Febco 805YD series was introduced approximately 1988. It is produced in the 2 1/2"-10" sizes. In the Febco 805YD the body material was changed to ductile iron. In 1991 a fused epoxy coating was added to replace the painted epoxy coating which was used up until that time. The check seats are replaceable. The seat design was changed so that no special tool was required to replace the seat. The 2 1/2"-3" have springs that are contained. The 4"-10" have contained springs.

    850 / 850U / LF850 / LF850U

    Febco 850 double check assembly. The 1/2"-2" sizes began production in 1997. The body is made of bronze and is an in-line modular check design. The check modules are made of glass filled Noryl and held in the body by a center retainer. The model Febco 850U has a union end ball valve on the model Febco 850. In 2000 the model Febco 850B was developed as a bypass for the model 831.
