1. INTRODUCTION
The VD510-SS is a diaphragm valve designed for precise flow control of low to medium viscosity
materials (under 10,000 cps). The valve head is made of Stainless Steel appropriate for use in
medical grade applications. Shot sizes may be fine tuned by turning the stroke adjustment knob at
the top of the valve.

Dispensing OFF
Dispensing ON
short
Stroke
long
small
Shot Volume
large
In the “Normal”state (air off), the diaphragm
is closed –material is not dispensed.
When air is applied, the diaphragm is opened and
material is dispensed.
Because "Air" is not entering into the driving
parts, the diaphragm is closed. In this case,
the material path is closed, so material is
not dispensed.
If air is applied to the valve, the diaphragm will open.
At this time material will be dispensed.
You can increase or decrease the shot volume by
adjusting the stroke (shot volume control knob).
Notice
The maximum stroke length is 0.6mm (1
rotation). There is no effect after turning the knob
more than (1) rotation.

5-1-1) Fasten the valve firmly using mount hole.
(M5*P0.8*D98)
5-1-2) Connect air hose to Air In Port and Controller.
Valve driving pressure is Min 4.0kgf/㎠or more.
5-1-3) Connect fitting for material supply hose to the inner port (BSPT1/8")
Notice
Do not insert fitting too deeply (7 ㎜or more).
5-1-4) Connect a suitable sized needle to the outer port.
5-1-5) Adjust the material pressure (max 5.0kgf/㎠).
When dispensing low viscosity materials (like water, solvent) set material pressure at 0.5kgf/㎠. For
high-viscosity materials, set material pressure at 2.0kgf/㎠.
Increase or decrease pressure as needed.
5-1-6)
At the time of delivery, the scale of shot volume control knob is being initiated
to point 3(½of full stroke). Increase or decrease the number as needed.
Maximum length of stroke is 0.6 ㎜.
(This is corresponding to the amount when shot volume control knob makes 1 round).
Notice
If you make 2 or more revolutions counterclockwise, the tensile strength of spring
is weaker and the valve becomes open state all the time. In this way liquid can
be dispensed.

5-1-7)
After steady mode in controller and reducing pressure of pressure container,
make dispensing the liquid come out slowly.
(This is to remove bubble and dispense the first liquid from valve)
5-1-8)
Choose "timer" or "steady" mode of controller according to the state of dispensing.
5-1-9)
You can control dispensing amount by selecting 1 of following 4 options.
▶4 options
By increasing or decreasing pressure to
container
Pressure increase →Dispensing amount increase
Pressure decrease →Dispensing amount decrease
Thickness of Needle
Thick Needle →Dispensing amount
increase (Improvement of tendency to pause)
Thin Needle →Dispensing amount decrease
(Worse of tendency to pause)
Flux Control Knob
Long stroke →Dispensing amount increase
Short stroke →Dispensing amount decrease
Dispensing Time
Long dispensing time →Dispensing amount increase
Short dispensing time →Dispensing amount decrease
*Choose the way of controlling dispensing time preferentially to get proper dispensing amount.

5-2. Maintenance
5-2-1) Washing
①Wash valve thoroughly after using if dispensed liquid has tendency to be stiff
or has possibility to damage liquid contacting part.
②First of all dispense all liquid entirely from pressure container,
liquid supply hose and liquid contacting part until sufficient air comes out.
③Wash liquid inside of valve with a little of proper solvent.
④Then wash thoroughly in order of air→solvent→air→solvent.
5-2-2) Disassembly
①In case of disassembly for washing or replacing part,
Refer to "7.Exploded View & Parts List".
②In case of washing valve head with sharp pin or
others, try not to scratch needle or seat part. If
damaged you need to replace parts because of
leakage.
5-2-3) Assembly
①Diaphragm Assembly
ⓐLoosen stroke control knob by turning twice counterclockwise.
ⓑSeparate valve head.

ⓒRemove diaphragm by turning counterclockwise.
ⓓScrew new diaphragm carefully to become horizontal to piston road screw-thread.
- 7 -
Notice
If it isn't fit thread properly leakage may occur.
ⓔAfter fixing diaphragm at regular intervals(0.4mm) like the picture,
for matching cylinder body and mount screw, please turn to the
location that you want using a screwdriver like next picture.
ⓕTo reinstall valve head fasten L(hexagon)-wrench bolt firmly.
ⓖFasten stroke control knob until it is closed.
Then open it again until stroke is appropriate.
Notice
Scale may not indicate to ‘0’of reference mark. In this case refer to relative scale.
(No problem to use)
