New High-Speed Modular Jet Valve for Micro-depositing Adhesives

Posted on 6/27/2019 7:23:17 AM By ASC

Nordson EFD has launched a modular jet valve it says is capable of dispensing precise and repeatable micro-deposits of liquids, including sealants and adhesives, at a continuous speed of 1000Hz, and at bursts of up to 1500Hz.

According to the company, the PICO Pulse delivers precise micro-deposits as small as 0.5nL on any surface, as well as in the most demanding production areas, including those which are uneven and hard to reach. Precise dispensing is attained by variable stroke control, and production demand changes are accomplished through the jet valve’s modular design.

Nordson reports that this modular design approach and the latch free mechanism in the jet valve meant less down time when it came to servicing the valve, or exchanging wetted parts that come into contact with the medium under pressure. It also allowed for the jet to be used to dispense a wide range of assembly fluids with different viscosities or movements of flow.
