K-FLO 47 Series With L2 Epoxy Retained Seat

Crispin/K-Flo is pleased to announce that customers now have more than an "either/or" choice when selecting a Seat-In-The-Body AWWA Butterfly Valve. The same great K-Flo 47 Series large diameter butterfly valve is now available with an epoxy retained rubber seat. An industry favorite for over 30 years, the epoxy retained seat provides full port flow equal to or greater than all major leading valve designs. Available in sizes from 24" to 96".

Instead of casting a step in the body designed to receive the seat and retaining hardware of our standard 47 series valve seat, we machine a dovetail groove in the body to accept the seat extrusion. Next, a special 2-part epoxy is injected behind the seat and into the groove. This epoxy will not bond to the seat extrusion nor the body groove.

With the disc in the closed position, the epoxy pushes the extrusion out to make a solid seal against the full circumference of the disc. Once hardened, the epoxy maintains the ideal interference between the seat and the disc thus producing an excellent long-term sealing option.
