The 781S Series Low Volume Low Pressure (LVLP) spray systems apply consistent
coatings of low- to medium-viscosity uids exactly where needed.
Microliter to milliliter amounts can be reliably dispensed in round patterns with
diameters ranging from 4.3 to 50.8 mm (0.17 to 2.0") and in fan patterns with
widths up to 165.1 mm (6.5").

Spray Valves
781Mini Series
Spray Valve
Features and Benets
• Improved uniformity for better
accuracy and ner edge denition
• Narrower spray patterns as small as
1 mm (0.04") wide
• QR (Quick Release) clasp for tool-free
serviceability in seconds
• High transfer efciency with no
overspray
7364002 781Mini-0.01" Valve
Features a 0.254 mm (0.01") nozzle orifice.
Round pattern, narrow angle.
7362301 781Mini-0.03" Valve
Features a 0.76 mm (0.03") nozzle orifice.
Round pattern.
The 781Mini
™
precision Low Volume Low Pressure (LVLP) spray valve’s innovative
design produces an exceptionally more uniform, narrower spray pattern than
previously possible.
Its 60% smaller form factor allows it to dispense in tighter, more complex spaces,
and to mount more valves per xture plate for increased throughput.
Narrow spray patterns
as small as 1 mm wide

MicroSpray Valve
Features and Benets
• High transfer efciency
• No overspray or mist
• Consistent spray pattern
• Faster throughput
7029409 787MS-SS Valve with Centering
Air Cap
Accommodates Tip Centering Guide. Includes spray
tip kit, air hoses, fluid inlet fitting, barrel reservoirs,
and adapter assembly for reservoir pressure.
7012549 787MS-SS Valve
Does not accept Tip Centering Guide.
The 787MS-SS precision spray valve uses Low Volume Low Pressure (LVLP)
technology to produce uniform spray patterns between 3.3 mm (0.130") and
19.1 mm (0.75") in diameter.
Innovative design uses a small gauge 0.3–0.1 mm (0.013–0.004") ID disposable
dispensing tip in place of a standard spray nozzle. This concentrates the LVLP air
used to atomize the coating into uniform spray patterns as small as 3.3 mm (0.130")
in diameter — over 30% smaller than EFD’s standard spray valve conguration.
TIP CENTERING GUIDE
The Tip Centering Guide ensures proper
alignment of the dispensing needle in critical
spray applications. Order components separately.
