Table 1: Component Descriptions
• Pneumatically Operated Dose Valves for component A and B
• Purge Valves for solvent and air purge
• Sampling Valves for calibrating the flow meters and performing ratio checks
• Shutoff Valves for component A and B to close their fluid passages to the mix manifold, to
allow for accurate calibration and ratio checks
• Mix Manifold, which includes the fluid integrator and static mixer.
 Fluid Integrator is the chamber where component A and B align at the selected
ratio and begin to mix.
 Static Mixer has 24 elements to uniformly blend the materials downstream of the
fluid integrator.
The following optional flow meters are available from Graco:
• G3000 is a general purpose gear meter typically used in flow ranges of 75-3800 cc/min.
(0.02–1.0 gal/min.), pressures up to 4000 psi (28 MPa, 276 bar), and viscosities of
20–3000 centipoise. The K-factor is approximately 0.119 cc/pulse.
• G3000A is a gear meter for use with acid catalyst fluids. It is typically used in flow ranges
of 75-3800 cc/min. (0.02–1.0 gal/min.), pressures up to 4000 psi (28 MPa, 276 bar), and
viscosities of 20–3000 centipoise. The K-factor is approximately 0.119 cc/pulse.
• G3000HR is a high resolution version of the G3000 meter. It is typically used in flow
ranges of 38–1900 cc/min. (0.01–0.5 gal/min.), pressures up to 4000 psi (28 MPa, 276
bar). and viscosities of 20–3000 centipoise. The K-factor is approximately 0.061 cc/pulse.
• S3000 is a gear meter used for solvents in flow ranges of 38-1900 cc/min. (0.01–0.50
gal/min.), pressures up to 3000 psi (21 MPa, 210 bar), and viscosities of 20–50 centipoise.
The K-factor is approximately 0.021 cc/pulse. Required to use the Solvent Push feature.
• Coriolis is a specialty meter capable of a wide range of flow rates and viscosities. This
meter is available with 1/8 in. or 3/8 in. diameter fluid passages. For detailed information
on the Coriolis meter, see manual 313599.
The K-factor is user-settable; at lower flow rates use a lower K-factor.
 1/8 in. fluid passages: set K-factor to .020 or .061.
 3/8 in. fluid passages: set K-factor to .061 or 0.119.
An optional component. It is available as a color change valve stack for either low or high pres-
sure with up to 30 color change valves. Each stack includes one additional valve for solvent to
clean the fluid line between color changes.
An optional component. It is available as a catalyst change valve stack for either low or high
pressure with up to 4 catalyst change valves. Each stack includes one additional valve for sol-
vent to clean the fluid line between catalyst changes.
A different catalyst change valve is used on acid catalyst systems.
Used to communicate between the EasyKey and Wall Mount Fluid Station.
Used to provide power to the Wall Mount Fluid Station.
Air Flow Switch: The air flow switch detects air flow to the gun and signals the ProMix control-
ler when the gun is being triggered. The switch functions with the flow meters to ensure that
the system components are functioning correctly. See the system operation manual for further
information.
Gun Flush Box: The gun flush box kit provides an automated flushing system for manual
spray guns, and includes an air flow switch.
