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

• 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.

7021649 782RA Radial Spray Valve
Rotor length is 5.59 cm (2.2") and reaches into
cylinders with a minimum inner diameter of 2.54
cm (1.0"). Includes fluid inlet fittings #7021499
and #7007038.
Fluid body and rotor are hard-coat anodized
aluminum. Each valve can be calibrated with the
stroke reference knob for process control. Radial
valves include fluid inlet fittings and two 1.5 m
(5 ft) control air hoses with fittings to connect the
valve to the ValveMate 7160RA controller.
Unique design uses a precision air motor and Low Volume Low Pressure technology
to apply a uniform coating of lubricants, primers and other low- to medium-viscosity
uids inside cylinders 25.4 mm to 304.8 mm (1" to 12") in diameter.
