Component

Description

 

 

Fluid Manifold (FM)

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

 

 

Flow Meters (MA,

Four optional flow meters are available from Graco:

MS)

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

An optional component. It is available as a color change valve stack for either low or high

Valves (ACV) and

pressure with up to 30 color change valves. Each stack includes one additional valve for

Color Change

solvent to clean the fluid line between color changes.

Module (CCM)

 

 

 

Dual Fiber Optic

Used to communicate between the EasyKey and Fluid Station Control Box.

Cable (FO)

 

 

 

Fluid Station

Used to provide power to the Fluid Station Control Box.

Control Box Power

 

Supply Cable (PS)

 

 

 

Flow Control

Includes an air operated fluid pressure regulator, fluid pressure sensor, voltage to air

Regulator

pressure transducer and circuit board. The function of this unit is to receive the flow ana-

Assembly (FC)

log signal and drive (manage) the desired flow rate.
