DEFINOX was founded in 1968 within a large industrial group based in the Vendée. At this time, its main activities centred on applications for the dairy industry.

The nineties were a turning point for DEFINOX, with the advent of the first Double Sealing Changeover Valve, the “VDCI”. This opened up other markets for DEFINOX products, such as the brewing industry, and DEFINOX established its reputation as a designer and supplier of high-tech process valves.

In 2010, the DEFINOX division was hived off and DEFINOX SAS set up, focusing its activities on three major areas:


  • Conception and manufacturing of process valves
  • Dedicated customised manifolds
  • Advise and servicewith the PackServices creation

All our products are designed and manufactured in France in Loire-Atlantique region (44). Our research and development department, in close collaboration with production and marketing & sales, is constantly at work on product improvements and innovations.

Our motto: customer satisfaction comes first!
