The valve standard for high-purity processes.
Hygienic diaphragm valves, pinch valves, sampling systems, and custom-fabricated stainless steel. Engineered in America since 1996.
Standard ships from stock · custom 6–8 weeks
Why we've been chosen for 30 years.
Purpose-built for purity
We don't convert industrial valves to hygienic use. Every valve is conceived and executed specifically for high-purity processes, from the integral sealing ridge to the proprietary diaphragm extrusion.
Made in America since 1996
Every valve, every fitting, every custom-fabricated assembly is engineered and manufactured at our Carson City, Nevada facility. Same engineers. Same QC standards. For 30 years.
Real proprietary technology
Tork-Tite® Feet, Valbow®, eMaxion Actuator, Integral Sealing Ridge. Patented innovation, not marketing slogans, that solves real biopharma and high-purity engineering problems.
Trusted globally, supported locally
Distribution partners worldwide. Direct engineering support from Nevada. We pick up the phone.
Engineered to a different standard.
Not industrial valves adapted for hygienic use. Hygienic valves designed from a blank sheet, for every high-purity industry that demands them.

Three ways to actuate. The ARTēVA® pinch valve series.
One proven 316L stainless steel pinch head. Electric, pneumatic, or manual. Reusable mechanism, single-use tubing.
Every machined cut, every weld, every certificate. Engineered in-house.
Aquasyn’s US facility combines advanced machining with hands-on fabrication expertise. From concept drawings to finished assemblies.
Advanced Machining
Five-axis centers, 316L bar stock, ±0.005″ as standard. Standard configurations ship from stock, made-to-order in 4–6 weeks.
Welding & Finishing
Orbital heads on tube joints, hand welding where the geometry demands it. Finishes from 25Ra to 5Ra, electropolished in house.
Engineering & Design
SolidWorks, AutoCAD and NX-Ideas. Fully detailed drawings for approval before anything is cut, with CFD on request.
Documentation & Quality
EN 10204 3.1 material test reports and heat numbers as standard. Weld maps, profilometer readings and passivation certificates on any order.
Exotic Materials
Beyond 316L: Hastelloy® C-22 and AL-6XN® for aggressive acid and high-chloride service.
Assembly & Testing
Bodies, diaphragms and actuators built and function-tested on the same floor that machined the parts.
Process specialists in bioprocessing.
In 2026, Aquasyn joined Alphinity, a bioprocessing platform engineering precision fluid handling for next-generation biotech. Aquasyn is the stainless-steel hygienic backbone of a portfolio that spans single-use components, bespoke systems, and end-to-end process engineering.

VannX™
Patented engineering that defines the category.
Tork-Tite® Feet
Bonnet feet hold the diaphragm in fixed position with controlled compression. Zero leakage. Extended diaphragm life.
Valbow®
Integrated valve and elbow assembly. Combines valve and elbow fitting in one. Reduces fittings, leak points, and dead leg.
eMaxion Actuator
Actuator system engineered for automated valve operation. Precision-aligned to our diaphragm valve body.
Integral Sealing Ridge
Machined directly onto the valve body at the flow chamber intersection. Eliminates entrapment crevices.
30 years of hygienic engineering.
And we're just getting started.
From a sketch on a futon in 1996 to the Smithsonian Institution in 2013, Aquasyn has stood for one thing: hygienic valves and fittings purpose-built, not converted. This is our 30th year, and our most ambitious chapter yet, joining the Alphinity family of bioprocessing innovation.
From the floor and the field.
Engineering notes, company news, trade-show updates, and technical articles from the team that's been building hygienic valves for 30 years.
Aquasyn joins the Alphinity family. A new chapter at 30.
Sister companies for years, now formally integrated. What the relationship means for our customers, our distributors, and the future of hygienic fluid handling.
