Valbow Valves

The Valbow® was created some years ago as a solution to one of our customer’s unique problems. It has evolved into a popular Aquasyn product and is stocked in a variety of sizes. The Valbow® is uniquely suited for that one spot where nothing else will do. Whether it’s a hard to reach sample valve on an R/O system, or for a directional change valve on a Bioreactor, valbows just seem to come in handy.

The Valbow® 90-degree valve was created to fit where nothing else can. Handy as a sample valve on an R/O system or as a directional change on a bioreactor, the Valbow® offers minimal hold-up volume, as well as sampling capability. Available connections include: hygienic clamp, orbital weld and end cap.

Aquasyn’s Sample Bottle, ideal for situations when reusable components are preferred, assemblies are available on bottles ranging in size from 50mL to 1000ML. Fully auto-clavable, the sample bottle assembly features a lightweight Valbow® 90-degree valve.
