VannX™ vs. Vannefold™ – What’s the Difference?
VannX™ is the individual motorized diaphragm valve. It consists of one disposable valve body (wetted fluid path) and one reusable high-precision motorized actuator. Each VannX™ provides accurate, repeatable flow control at a single point in your process.
Vannefold™ is a compact valve block that integrates 2–5 VannX™ valves into a single machined polypropylene unit. The valve bodies are molded or machined directly into the block, creating very short internal flow paths, minimized center-to-center port spacing, and significantly lower hold-up volume than individual valves connected with tubing and fittings. Each valve position still has its own reusable actuator.
In short:
Use VannX™ for single-point control (one valve in a line, bypass, inlet/outlet, etc.)
Use Vannefold™ when you need multiple valves close together (manifolds, multi-way flow paths, series/parallel setups, perfusion circuits, chromatography skids)
Both share the same core advantages: disposable fluid path, reusable precision actuator, no pneumatics, low hold-up, and excellent chemical compatibility.
Next-generation single-use diaphragm valves purpose built for modern bioprocessing
VannX™ is a compact, motorized diaphragm valve that brings exceptional control and efficiency to downstream biopharmaceutical applications.
It delivers ultra-precise, repeatable diaphragm positioning — enabling very tight control of transmembrane pressure (TMP), flow rates and back pressure that today’s sensitive biologics require. The optimized internal geometry significantly reduces hold-up volume, enhances complete product recovery and prevents unwanted closures from chemical swelling — even at high concentrations.
The fluid-contact path (valve body and diaphragm) is fully single-use — ensuring sterility and eliminating cross-contamination risk — while the compact, reusable 24 V DC motorized actuator removes the need for compressed air infrastructure entirely.
Fully automation-ready and Pharma 4.0 compatible (encoder feedback, IP65 protection, M12 connectivity), VannX™ integrates seamlessly into modern control systems.
Compared to traditional pinch valves, VannX™ and Vannefold™ offer cleaner flow geometry, dramatically lower hold-up volume, higher product yield, consistent performance without tubing fatigue, and complete elimination of compressed air systems — all while maintaining full compatibility with single-use workflows.

Frequently Asked Questions
-
VannX™ is a single-use, motorized diaphragm valve designed for precise, sterile fluid control in biopharmaceutical manufacturing.
It uses high-resolution motor actuation to deliver stable, repeatable flow and pressure control while eliminating the need for compressed air or reusable actuators. -
Unlike pneumatic or hybrid motorized valves, VannX™ is fully single-use, including the actuator — removing cleaning, sterilisation, and revalidation requirements.
It combines:
Compact, low-profile geometry
High-precision motor control (thousands of steps)
24 V DC operation (no compressed air)
Automation-ready encoder feedback
This results in smaller systems, better control, and simpler validation.
-
