Component Identification and Definition
312775G 11
Fluid Manifold (FM)
• 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 mani-
fold, 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.
Flow Meters (MA,
MB, MS)
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 viscosi-
ties 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 centi-
poise. 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.
Color Change
Valves (ACV) and
Color Change
Module (CCM)
An optional component. It is available as a color change valve stack for either low or high
pressure with up to 30 color change valves. Each stack includes one additional valve for
solvent to clean the fluid line between color changes.
Catalyst Change
Valves (BCV)
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 solvent to clean the fluid line between catalyst changes.
Dual Fiber Optic
Cable (FO)
Used to communicate between the EasyKey and Wall Mount Fluid Station.
Fluid Station Power
Supply Cable (PS)
Used to provide power to the Wall Mount Fluid Station.
Applicator
Handling: use Air
Flow Switch (AFS)
or Gun Flush Box
(GFB)
Air Flow Switch: The air flow switch detects air flow to the gun and signals the ProMix
controller 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.
