FEBCO 860 2 1/2-8" RV ASSEMBLY

Relief Valve Kit for 2 1/2 to 10 IN Reduced Pressure Zone Assembly, Series 860

Model Overview

This is a reduced pressure assembly. The 1/2"-2" sizes began production in 1997. The body is made of bronze and utilizes an in-line modular check design. In 2010 a LF860 model was introduced in sizes 1/2"-2" which was constructed of lead free bronze. The checks are accessed from a single cover on the top. The check modules are made of glass filled noryl. The relief valve utilizes an internal relief valve sensing line. The model 860U incorporates a union end ball valve on the 860. The 880 in sizes 1/2"-2" utilizes an N shape piping on the end of the model 860. The 880U incorporates a union end ball valve on the end of a model 880. Production on sizes 2 1/2"-10" began in 1993. The check body is made of ductile iron which is fused epoxy coated. Check springs are contained when the cover is removed. Check seats are replaceable. The internal check mechanism is a swing check design with the internal parts made mostly of bronze. The check disc utilizes a vulcanized clapper plate design of elastomer seal. The relief valve is attached to the check body by a flange. The RV body is made of bronze. The RV spring is contained when the RV cover is removed but spring tension must be released for proper repair. The three different models (860,880,880V) utilize similar repair parts for the components of the assembly. The 860 model is a straight horizontal configuration. The 880 is known as the N shape. The piping comes up from the bottom on the inlet and goes down out of the outlet to give it a compact installation feature. The 880V is a vertically oriented assembly where the piping comes up into the inlet and then goes horizontally through the check mechanisms. The outlet continues to go up out of the outlet check to give it a vertical orientation. In 2011 the LF 860 and LF880V were introduced. The internal check mechanism was changed to a lead free design. The previous leaded bronze items were changed to stainless steel or other lead free materials. The internal check utilizes a silicone disc instead of the vulcanized clapper plate as in the 860 and 880 design. The relief valve body was changed to epoxy coated ductile iron.
