Introduction - Graco Dispensit 1230 Instructions Manual

This manual is for the 1230 Series Positive Displacement Dispense Valves, designed and manufactured by
Dispensit. This manual addresses the setup, operation, maintenance and adjustment of all aspects of the
valve, which will be useful for management, support technicians as well as the operator.
Its design also permits quick change out of the wetted module (wet head), allowing the drive module
(power head) to remain permanently fixed to its mounting, assuring a minimal downtime for material
change or replacement. The valve has a linear shot adjustment scale which provides volumetric
consistency in shot applications.
The 1230, made of corrosion resistant plastic and has either plastic or stainless steel metering rods and is
offered in three different Metering Rod sizes and volume output ranges. The .125 valve has a dispense
range of 0.010cc's-0.126cc's, the .188 valve has a dispense range of 0.022cc's-0.283cc's, and the .250
valve has a dispense range of 0.040cc's-0.503cc's.
The 1230 will allow the operator to place a precise amount of material on a specific part with excellent
repeatability, with cycle times as fast as 1.5 shots per second (depending on the application). This valve is
capable of handling pressures, up to 60psi (.41MPa), and non-metallic material viscosities ranging from
water type materials to medium viscosity fluxes. Material can be supplied by means of different types of
material transfer systems, ranging from low-pressure syringes or cartridges to 55-Gallon transfer pump
systems.
The 1230's modular design and lightweight allow it to easily integrate into a variety of applications. The
valve is most commonly mounted vertically (with two 8-32 machine screws) however; it may be necessary
to mount it at other angles, depending on the application. This valve has a variety of uses ranging from a
simple bench top dispense system to robotic cells or conveyorized systems. This valve can dispense
through a single luer lock needle, or a custom designed needle block configuration.
NOTE: Mounting the valve vertically will enable the use of the wet cups, while mounting the valve on an
angle will disable the use of the wet cups.
Safety considerations are an extremely important element in the proper operation of this dispense valve.
Actively thinking about the safety of yourself and others, as well as the condition of the equipment, is of
most importance. Regard all warnings, cautions, and notices that are listed (on the left margins) throughout
this manual and in any accompanying literature.
To avoid damage to property, equipment, and/or personal
injury, please adhere to common safety practices. Failure
to do so may result in such damage or injury.
