Working With Challenging Samples
Finding and Eliminating leaks
Mini Rotary Valve are commonly used in many system to switch flow path or for sample injection. Drop in replacement for what’s available on the market but with several advantages that makes it leak tigh and long lasting.
- Treated Rotor. No-sticking action
- Low rotational force
- Mounting collar design for anti-rotation assembly
Extended pin design drive adaptor (double stop pin for no radial)
The first real analytical tight shut-off diaphragm valve family. They can be used in multiple places in gas chromatographic systems, auto-samplers, sampling and general instrumentation. No dead volume effects, continuous flowpath and purge system make them ideal in many situations. From simple 3-way to complex configuration with timing sequence, the job is easily done.

Fittings are critical components in any analytical system. This is why AFP put some extra work on small detail in order to launch our high performance analytical grade fittings. The level of sealing and the need for zero dead volume were taken into consideration when designing these fittings. Which are available in different sizes and material.

Short Tutorial and Technical Notes
All valves and fittings are manufactured in North America under strict conditions. Most of them are done inside our sister company APN where they are assembled and tested under the control of our ERP system, the Meta4.0, which gives us the possibility to custom tune every valve to the perfectly fit of the customer application.
