*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).
