The Disc Holders used in the 4” AquaMatic valves series 428 and AV8 will be changing material from Aluminum Bronze to 303 Stainless Steel. The dimensional characteristics of the parts will remain the same and they can be used interchangeably. As a result, the Aluminum Bronze parts will be obsoleted and replaced with the Stainless parts in both valves and kits.
