Dispensing valves

The interaction of the flexible dispensing heads with a whole range of different dispensing valves makes the dispenseALL420 a universal solution for dispensing and jetting. In addition to our standard valves, many customer-specific dispensing valves can be integrated into the machine. Just contact us, together we will find a solution.

 

Time-pressure dispenser valve

Its simple construction makes the valve particularly robust and low-maintenance. A pre-set pressure acts on the syringe for a short time. The desired dispensing is simply set in the software.

 

Typical applications

  • Forms
    Points, lines, circles, contours
  • Media
    Solder paste, glue, underfill, sealants and similar

Technical specifications

  • drive
    pneumatic
     
  • dispensing principle
    time pressure
     
  • dispensing speed
    3.600 dots/h
     
  • viscosity range
    pasty

Precision dispenser valve

The precision dispenser valve also records parameters such as temperature and syringe level. The processor control uses these values to control the pressure and the time of the dispensing pulse in order to achieve the highest repeatability. Media volumes from 0.001 to 5 mm³ can be dispensed reliably.

The processor control makes it possible to keep the mechanical structure of the dispensing valve extremely simple. Thus, the valve remains robust and low maintenance despite highest accuracy.

Typical applications

  • Forms
    points, lines, circles, contours
     
  • Media
    solder paste, silver cunductive paste, Underfill, fill and dam material

Technical specifications

  • drive
    pneumatic
     
  • dispensing principle
    time pressure incl. processor control
  • dispensing speed
    3.600 dots/h
     
  • viscosity range
    watery to pasty
     
  • options
    • level compensation
    • retention vacuum (suck back)
       

Screw dispenser valve

Suitable for precise dispensing of medium-viscosity media such as SMD glue, solder pastes or silver conductive paste. Gentle, the rotation of a spindle inside the valve supplies the medium. This minimizes the pressure load on the medium.

 

Typical applications

  • Forms
    points, lines, circles, contours
     
  • Media
    solder paste, silver conductive paste, glue, fill and dam material

Technical specifications

  • drive
    DC-motor
     
  • dispensing principle
    screw conveyor
     
  • viscosity range
    50.000 mPAs to pasty

Jet-dispensing-system

The advantage of the piezo dispensing valve in jet dispensing is its high dispensing speed. With a dispensing frequency of up to 150 dots per second, it is possible to apply even smallest amounts starting from 2 nl.

 

Typical applications

  • Forms
    points, dotted lines

  • Media
    glue, fill and dam material

Technical specifications

  • drive
    electro-pneumatic
     
  • dispensing principle
    volumetric
     
  • viscosity range
    pasty, 50 up to 2.000.000 mPAs

Spray valve

Low to medium-viscosity media such as oils, release agents, alcohol or activators can be dispensed by a spray valve. The valve is designed to be connected to a separate fluid container so that the medium is always available in sufficient quantities. Level sensors and pressure monitors ensure permanent monitoring of the spraying process.

 

Typical applications

  • conformal coating
  • coatings
  • solvents
  • oils
  • activators

Technical specifications

  • drive
    pneumatic
     
  • dispensing principle
    atomization
     
  • viscosity range
    50.000 mPAs up to pasty
