Overview
Overview
Usage
The Graco ProControl 1KS is an electronic flow control and color change system, for use with most solvent and
waterborne epoxy, polyurethane, and acid-catalyzed paints. It is not for use with "quick-setting" paints (those with a
potlife of less than 15 minutes).
•
Has user selectable ratio assurance and can main-
tain up to +/-1% accuracy, depending on materials
and operating conditions.
•
Models are available to operate air spray or
air-assisted systems with a capacity of up to 3800
cc/min.

Table 1: Component Descriptions
Used to set up, display, operate, and monitor the system. The EasyKey accepts 85-250
VAC, 50/60 Hz line power and converts that power to acceptable low voltage and optical
signals used by other system components.
Includes air control solenoids. Its control board manages all fluid functions.
Includes wall mounting bracket and mountings for the fluid meter and the following
valves:
•
Pneumatically Operated Dose Valve for component A
•
Purge Valves for solvent and air purge
Four 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.
•
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 options are available for low pressure
(300 psi [2.1 MPa, 21 bar]) air spray and high pres-
sure (3000 psi [21 MPa, 210 bar]) systems with up
to 30 color change valves and up to 4 catalyst
change valves.
NOTE: Optional accessories are available for in field
installation to achieve 30 colors.
