ELDV-MDVG

Gas chromatographic diaphragm valve

Our Gas Chromatographic diaphragm valve with the only embedded patented purge system is our most popular products. Fully loaded with innovative feature this is the number one choice of the leading Gas Chromatograph makers.

Ensemble-ELDV

MRV-Series

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.

DV-SERIES

DIAPHRAGM VALVE FAMILY

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.

FITTINGS

  • Standard fittings

    Here we are offering a line of fittings that have, by design, improved characteristics. Internal finish, ferrule design, thread finish are some of the characteristic that have been improved. Practical details, like stackable crosses and tees, eliminate the need of mounting clamps and allow space saving. Low torque column end fittings and unions make 1/8" OD and 1/4" OD size tubing assembly much easier and better. Available in several materials and custom designs to fit OEM needs.

  • analytical fittings

    For several decades, fittings have been the same. Fittings are critical components of any analytical system. The level of sealing, dead volume or mechanical characteristics could vary dramatically based on manufacture process, even if externally they look the same. But don’t get fooled; there are serious differences between them. Nothing looks more like a fitting than another fitting! Differences reside in details.

Tubes

TUBES FAMILY

AFP will be stocking handytube’s ultra-small diameter (usd™) capillary tubing. That is precisely engineered for chromatography, flow measurement and sensing. Applications. they can withstand over 36,000 psi (2500 bar). Our careful design and tight manufacturing specifications create smoother, cleaner capillary tubing with consistently uniform id characteristics.

MANUFACTURING

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.
