Aquasyn Sanitary Diaphragm Valve

Sanitary Valves



Meet Aquasyn—the new standard in high-purity valves designed specifically for the unique needs of biopharmaceutical manufacturing. Rather than just rebrand an industrial valve for sanitary applications, Aquasyn has developed proprietary technology to meet the demanding requirements of the biotech industry.

Sanitary Valves
Biotech & Micro-Bio Series

The only small-frame valves for the biopharmaceutical industry, Aquasyn diaphragm valve bodies come in ¼” 3/8” and ½” nominal sizes. These fractional-sized valves are a popular alternative when space is at a premium, such as small-scale bioreactors, filtration and chromatography skids and freeze-thaw systems. The Micro-Bio diaphragm valve is roughly the size of an egg and can accommodate 1/8”, 3/16” and ¼” nominal diameters, while still having the integral sealing features of Tork-Tite® feet.

Two-Way Valves

Aquasyn two-way diaphragm valves come in sizes ¼” to 6” and can be combined with a manual or pneumatic bonnet. The valve body is made from 316L austenitic stainless steel bar stock that is machined to ASME-BPE standards. The exterior body is sloped for easy cleanability and end connections are marked with drain angles to ensure proper alignment. All diaphragm valves are fully traceable with heat numbers and Material Test Reports (MTRs) provided with each shipment. Hastelloy, AL6XN and titanium versions are also available.

Sterile Access/GMP Combinations

Asquasyn valves can be uniquely crafted into any valve-to-valve or valve-to-fitting configuration with fast lead times. Sterile access and GMP combination valves are designed and assembled to minimize dead legs and maximize drainability.

Sample Bottle

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


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.


Now there is a product that combines a valve with a pressure transducer to take up little more space than a diaphragm valve. Aquasyn’s patent-pending instrumentation valve uses a self-draining hybrid block body style with Anderson Instruments’ CPM fitting to create a compact valve/instrument combination. The instrument is placed to the side of the valve weir, putting it in direct contact with process media and eliminating the concern of deadleg, common with traditional tee designs. Aquasyn instrumentation valves can also incorporate the following instruments: pH, DO, ORP, conductivity, UV/Absorbance and turbidity. Available in 1” and 1 ½” sizes.
