Graco A Series Instructions-Parts List Manual page 3

Complete systems are custom assemblies purchased
separately to fit your particular needs. Your Grace
representative can help you plan your custom MFC
DISPENSING MODULE A. Provides full control
over 1 fluid at any one of 12 Dispensing Stations.
Includes quantity selector and totalizer.
DISPENSING MODULE B. Provides full control
over 1 fluid at any one of 12 Dispensing Stations.
Includes quantity selector, totalizer, and individual
batch counter.
POWER SUPPLY MODULE. Provides power to
any number of Dispensing Modules and Fluid
Solenoid Valves. (Only three fluids can be dis-
pensed at one time from modules powered by a
single Power Supply Module).
JUNCTION STRIP. One strip connects 12 Dis-
pensing Stations, Pump Solenoid Valve, and Fluid
Meter to one Dispensing Module.
INTERCOM SYSTEM. For easy communication
between station operator and MFC control center.
(Optional, not a Grace supplied accessory).
AIR CONTROL VALVE. Provides easy on/off
control of air pressure to pumps from main air sup-
ply line.
MASTER AIR VALVE. Bleed-type valve isolates
Pump, Air Regulator and Air Solenoid Valve for
servicing, etc.
AIR REGULATOR. To limit pump output pressure
to 750 psi (52 bar) pressure if normal air supply
would make it higher.
System. Typically, the following components are
necessary. See page 8 for a more detailed explanation
of the Modules.

AIR SOLENOID VALVE. Electrical bypass valve
opens air line to start pump when activated by
Dispensing Module. (Optional-not required if
Pressure Relief Kit (MI is used.)
PUMPS. l:l, 5:1, and 1O:l ratio pumps can pro-
vide sufficient line pressure and fluid volume for
most systems. Other pumps also available.
FLUID METER. Electric meter sends l/lOth of a
quart or liter impulse to Dispensing Module
counter(s) as order is dispensed.
PRESSURE RELIEF KIT. Limits fluid pressure
build up in supply lines due to heat expansion, by
relieving fluid pressures over 900 psi (62 bar).
GATE VALVE. Isolates Pump and Fluid Meter
from fluid flow-back when servicing, etc.
FLUID SHUTOFF VALVE. Isolates Solenoid
Valve, and Dispensing Station for servicing, etc.
FLUID LINE FILTER. Protects Fluid Solenoid
Valve from harmful contaminants.
FLUID SOLENOID VALVE. Electrical bypass
valve opens fluid line to Dispensing Station when
activated by Dispensing Module.
DISPENSING STATIONS. Hose Reels or Dispen-
sing Bars; requires one reel or bar for each fluid
dispensed at each station. Available with fluid
solenoid valves and "ready" lights.
