About Precision Jetting Valve for Medium to High Viscosity Materials

The Vermes MDS 3200+ Jetting Valve System dispenses material in small volumes at fast speeds with extremely high accuracy and repeatability. The rising miniaturisation of individual components in production processes demand smaller beads and lines for dispensing whilst increasing production throughput, process reliability and consistent repeatability.

Based on piezoelectric fluid jetting technology, the Vermes MDS 3200+ allows for contactless application of materials at high speed with precision at a faster dispensing rate than those of pneumatic valve technologies.

We recommend the Vermes MDS 3200+ for dispensing medium to high viscosity materials up to 2,000,000 mPas in repeatable single dots or beads of ≥0.5 nl. Example fluids include SMT adhesives, conductive adhesives, silicones, LED phosphor, underfills, hot melts and solder pastes. These materials can be supplied to the valve via a choice of reservoirs, from 3ml to 55ml syringes or pressure pots.

For the dispensing of low to medium viscosity materials, please see the Vermes MDS 3010+ and Vermes MDS 3020+.

The system minimises initial set up with its top adjust design “Quickadjust” allowing for easy configuration and adjustment of the tappet and nozzle whilst an easy cleaning process reduces downtime, optimising production throughput and efficiency.

Specific to production requirements, components of the valves including tappets, nozzles and heating options can be customised to optimise the dispensing process of your application.

Features & Benefits


  • Opening and closing of the valve for max needle lift with more than 3000 Hz, nonstop operation with up to 1000 Hz


  • Suitable for high (up to 2,000,000mPas) viscosity materials
  • Freely adjustable parameter settings allow to customize the jet properties to the dispense fluid properties
  • Electronic control unit allows change of dispensing parameters quickly
  • Also suitable for low or medium viscous media (if the tappets are fast triggered or if the dispensing amounts are very small)


  • High repeatability of drop-to-drop dispensing volume for media of all viscosities
  • Dispensing into cavities, grooves and irregular surfaces


  • Converting the force of the latest generation piezo through sophisticated mechanics, the system can jet highest viscosity media with pressures of up to 1,000 bar


  • The modular design of the MDS 3200A allows user defined configurations for various applications. You can adjust the same system to very different process and fluid parameters with the exchange of just a few parts
  • You can use a number of different nozzle units for a wide range of media and dot sizes
  • For the optimum performance it is possible to choose from different tappet geometries
  • You can choose from several different fluid path materials, which allows for virtually unlimited media compatibility
  • Easy cleaning process reduces downtime of equipment
