Dymax SG-200 High-Flow Spray Gun System User Guide
a.
Pressure gauge that displays the pressure in the fluid reservoir. A 0- to 60-psi (0- to 4.1-bar) pressure
gauge is installed on the air regulator. Two alternative-scale pressure gauges (0-to-30 psi and 0-to-
100psi) are supplied and you can substitute these gauges for the installed gauge to match your
operating pressure requirements.
b.
Pressure control knob that enables you to adjust the pressure of the air entering the reservoir.
Compressed Air Line
—
The air line consists of transparent blue polyurethane tubing designed for compressed
air use.
Reservoir Retainer or Reservoir Tank
—
The SG-200 spray system is available in the following configurations:
a.
Cartridge Reservoir Retainer
—
A cartridge reservoir retainer is a plastic housing with a cover that holds
a cartridge reservoir. The top of the retainer seals the top of the cartridge reservoir. The bottom of the
retainer includes a hole from which the outlet port of the cartridge reservoir protrudes. Pressurizing the
top of the retainer pushes the cartridge reservoir piston down which pushes the fluid from the outlet
port.
b.
Bottle Reservoir Tank and Pail Reservoir Tank
—
Bottle and pail reservoir tanks are similar in
operational design. For example, you place an opened reservoir bottle (plastic polypropylene container
with a screw-on cap for bottle reservoir tanks or 5-gal (15-L) plastic polyethylene pails with a pry-off
cover for pail reservoir tanks) in the reservoir tank and seal the tank. A flexible or rigid dip tube with an
outlet on the tank cover is submerged in the fluid. When you pressurize the bottle reservoir tank, fluid
is driven up the dip tube and out of the tank for dispensing.
c.
Positive-Displacement Ram Pail Pumps
—
Ram pumps are ideal delivery systems for dispensing high-
volume and/or high-viscosity materials. Utilizing a check valve, positive displacement ram-style head,
and a downstream regulator, this system provides steady, even flow of material.
Dymax’s are d
esigned
for use with 5-gal straight and/or tapered pails.
Fluid Line
—
The fluid-dispensing line consists of black light-blocking polyethylene tubing compatible with the
chemistries of Dymax fluids and many types of commercial adhesives and fluids.
Handheld Spray Gun & Regulator Assembly
—
The handheld spray gun enables you to easily spray fluids and
provides trigger control with optional foot pedal override control. Spraying begins when the operator
squeezes the trigger and stops when the trigger is released
.
The atomizing function on the SG-200 is an
“always on” mode, ensuring the
heaviest materials atomize upon dispense. The spray gun includes a kit of
caps and nozzles of different diameters, allowing users to adjust per flow rates and materials being sprayed.
The spray gun assembly also includes two regulators. One for controlling the operating air for the gun and the
other for controlling the atomizing air used to create the spray.
DVC-345 Digital Valve Controller
—
The DVC-
345 digital valve controller’s
internal 4-way solenoid valve
operates Dymax or other pneumatic dispense valves. This controller may be operated via footswitch, manual
front panel switch, or remote PLC. Cycle time may be set in a range from .001 to 9.999 seconds in .001-second
increments. Front panel mounted controls provide a valve prime function, cycle adjustment, manual or timed
dispense, and a multi-color LCD timer display.
Spray Gun Stand
—
The spray gun stand provides a convenient way to hold the handheld spray gun in the
recommended position when it is not in use.
