Valve Selection Guide
Jetting / Dispense / Spray
Choosing the right dispense valve for an application starts
with the uid.
Use this guide to:
• See which Nordson EFD valves work with specic uids
and applications
• Compare the features of EFD valves and controllers
• Select a type of uid for an application
For example, if you know you want to use a jet dispensing
valve because of its signicant precision and fast cycle rate,
you could use this guide to identify the types of uids most
suitable for jetting.
Benets
• Performance that’s proven for millions of dispense cycles
• Long service life with minimal maintenance
• Worldwide technical assistance
• Global application testing labs
Please note this guide does not include every EFD
dispensing solution available. It’s important to speak with an
experienced EFD application specialist when choosing the
right solution for your application.

*Note: For microdot applications requiring general purpose tip sizes between 27 and 33 gauge, specify valve model xQR41 in place of 741V-SS. **Conditional use with cyanoacrylates.
Microdots: Any deposit having a
volume less than 5 µl (5 µl = 5 microliters
= 5/1000 cc).
Dots: Any deposit having a volume
larger than 5 µl.
Jetting: Applying microdots, dots, lines,
stripes, and encapsulates without making
contact with a surface – also called non-
contact dispensing.
Potting: Filling a cavity usually
containing an electronic device, electronic
circuit, or wires.
Encapsulating: Applying a coating to
an electronic component for protection from
mechanical or environmental damage.
Lines/Stripes: A line, bead or
stripe of material.
Filling/Packaging: Filling
containers such as small bottles,
cartridges, and tubes.
Microspray: Narrow spray pattern
capability as small as 1 mm (0.04”) wide.
Spray: Applying uids by using low
pressure air to break the uid into ne
droplets for coating or marking.
Internal Spray: Spraying the inside
diameter of holes and cylinders.

Important Note: For dispensing applications of low- to medium-viscosity uids where a 316L SS wetted uid body with aseptic uid ow
path is preferred, choose the 754V-SS diaphragm valve.

xQR41 for medium pressure only.
Maximum operating temperatures of EFD valves should not exceed 43° C (110° F) except for the
736HPA-NV, 741V, 781S, and 781Mini Series valves, which can operate up to 110° C (215° F).
