Wilkins Double Check Valve Assembly
Model 350ASTR (2-1/2" - 3")
With Stainless Steel Body & Spool - Replacement
Designed for drop-in replacement of existing longer lay length assemblies without the need for additional spools or spacers, saving 2 to 6 hours of installation labor and up to 2 machine hours per backflow replacement. A custom sized grooved spool installed between the backflow body and downstream shut-off valve allows customer specified assembly lengths to be shipped directly from the factory.
