BACKFLOW DIRECT DERINGER 40G 2 1/2" OSY

2 1/2 IN Stainless Steel Reduced Pressure Zone Backflow Preventer Assy, Deringer, OSY Shutoffs, Grooved Ends, Dual-Action Check Modules

Model Overview

This is a reduced pressure assembly. Production began in 2014 on the models 40 & 40X while production on the 40G began in 2018. The model 40 & 40X come with grooved end integral butterfly shut offs while the 40G comes with OSY flanged end shut offs. The body is a fabricated stainless steel design with a bolted single access cover. The checks are a modular design made of Noryl plastic material. The check discs are silicone rubber. The check modules are held into the body with bolts that extend from the outside of the body into a slot to hold the check modules in place. These allen head bolts have to be unscrewed to remove the check modules from the body for repair. The check uses a torsion spring design. Spring tension does not need to be released to change the check disc. The relief valve uses a stainless steel body that screws onto the bottom of the check body and uses an external relief valve sensing line. The relief valve uses a rolling diaphragm design with a silicone disc. The relief valve spring is contained when the relief valve cover is removed and is released by the removal of an e-ring on the relief valve stem.
