    positive displacement dispensing valvePositive displacement - also called volumetric - dispensing by nature
    ensures most consistent deposit sizes independent from environmental factors. Adhesives, for example, might change viscosity under changing ambient temperatures. Time/pressure dispensing will require continuous setting adjustments to keep the required volumes. Volumetric dispensing will not be influenced by these circumstantial factors at all. A valve system ensures consistent dispense action.
    There are different types of volumetric dispensing.


    The most common methods of positive displacement dispensing are: 

    • Rod metering valve systems that uses a rod which moves into a closed chamber
      displaces a precisely match of volume of fluid.

    • Rotary valve systems that use a pump with a lead screw rotating in a body to drive
      fuid between the screw threads out to the needle.

    Other available dispensing methods are:

    Single Component Time/Pressure Dispensing

    Two Component Dispensing

    Jet Dispensing

    Single Component Positive Displacement Dispensing Applications
    Applications in Single Component Positive Displacement Dispensing are solder paste dispensing, dam writing, single shot dispensing and filling dispensing, such as filling bottles, syringes, cartridges and cans.

    Single Component Positive Displacement Dispensing is applied in many industries, such as Automotive, Electronics & Solar Cells,  IT & Multimedia, Medical, Aerospace, Defence.
