The simple and reliable valves for large production

TexTexTex

Contexa SA has a large experience in volumetric and gravimetric dosing of liquids and powders.
The TEX valves are a gravimetric dosing system for liquids. The raw materials are weighed.
The raw materials are stored on a mezzanine.
A production formula is prepared in about 10 minutes on the TEX valves.
"Because the production time of a formula needs to be short and that the space at disposal is often restricted, we have designed a high performing and compact valve."

Main characteristics

  • Ideal for small to large production for formulas of a few kilograms to 1'500 kg (3'300 lb)
  • Production of formulas of 100 kg (220 lb) in about 10 minutes
  • Entirely adaptable linear flow. Opening possible between 0 and 100%
  • 30% productivity increase through automatic adaptation of the flow
  • Adapted for the dosing of fluid, viscous, heated and cooled-off materials
  • Pneumatic or mechanic actuation 60 valves per cluster
