Pure-Flo Zero Static Upstream Sample & Downstream Purge
The Zero Static Upstream Sample and Downstream Purge (ZUD) valve provides a single use point with multiple outlets that samples the upstream flow while purging and steam-sterilizing the downstream process from the same Zero Static valve. It uses a 0.5" Bio-Tek sample valve and a 0.5" Pure-Flo purge valve, with the sample outlet on a 0.75"-to-0.5" reducing ferrule to maximize drainability.
