Manual diaphragm valve DV-5625 Series
The valve DV-5625 is a diaphragm valve designed for precise flow control of low to
medium viscosity materials (under 10,000 cps). The valve is ideal for dispensing cy-
anoacrylates, reagents, electrolytes, glues, solvents, paints, alcohol and other volatile
substances. Shot sizes may be fine tuned by turning the stroke adjustment knob at the
top of the valve.

4 Operation Principles
Dispensing OFF Dispensing ON
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.
Since no control air is present,
the control parts of the valve are
at rest and the diaphragm is clo-
sed. This closes the material path
and no material is dispensed.
When air is applied to the valve, the dia-
phragm will open. At this time material will
be dispensed.
You can increase or decrease the shot volume
by adjusting the stroke (flow rate control
knob).
Notice
The maximum stroke length is 0,6 mm
(1 rotation). There is no effect after turning
the knob more than (1) rotation.

5 Operating Procedure
1. Fasten the valve firmly using mount hole (M5*P0.8*D98) or use a clamping ring
2. Connect the control compressed air hose to the controller and to the control air
input of the dosing valve. The control pressure for the valve must be at least 4,0 bar.
3. Connect the fitting for the material supply to the material inlet 1/8“ NPT thread.

Note:
Do not turn the fitting too deeply into the valve.
4. Place a suitable dispensing tip on the material outlet and fix it with the union nut.
5. Set the material pressure as follows (but max. 5.0 bar). Set the material pressure to
max. 0.5 bar if you want to dispense very thin material (such as water or solvents).
Set the material pressure for highly viscous material to approx. 2.0 bar and adjust it
according to the required dispensing.
6. On delivery, the adjusting screw is set to position 3 (center of full stroke).
Increase or decrease the setting as required. The maximum stroke is 0.6 mm.
This corresponds to a complete turn of the set screw.
Note:
If you turn the adjusting screw 2 turns or more often counterclockwise, the
return spring loses its effect and the valve opens continuously. This causes
the material to be dispensed continuously, even if no control pressure is
applied.
7. Adjust the valve, material pressure, and controller settings so that material slowly
exits the valve.
(This prevents bubbles from forming in the dispensing material during dispensing.)
8. Select the operating mode„Timer“ or„Manual“ on the controller depending on the
desired dispensing.
9. You can influence the dispensing result using the following 4 options:
Increase or decrease material
pressure
Pressure increase leads to increase
of dispensing quantity
Pressure reduction leads to a reduction
of the dispensing quantity
Diameter of dosing tip Thin dispensing tip reduces the dispensing quantity
Thick dispensing tip increases the dispensing quantity

Large stroke setting increases the dispensing quantity

7 Maintenance
7.1 Cleaning
Clean the valve regularly, especially if you are dosing material that is not intended to be
used for hardening, or can lead to possible damage to parts that come into contact with
the material.
First empty the material container so that the material path in the valve is as empty as
possible and air is still escaping.
Clean the accessible parts that come into contact with the material with a suitable
Clean or rinse the valve with a suitable cleaning agent.
Then flush the valve several times alternately with air and a liquid detergents.
7.2 Dismantling the valve
If it is necessary to disassemble the valve for cleaning, use the Exploded view and parts
list according to chapter 10.
7.3 Assembling the valve
Install diaphragm:
• Turn the adjusting screw counterclockwise out of the valve.
• Remove the valve head.
• Remove the old membrane by turning it counterclockwise.
• Turn in the new diaphragm carefully.
Note:
If the diaphragm has not been screwed in properly, the valve is leaking.

8 Detail drawings & dimensions
After you have brought the new diaphragm to the correct distance (0.4 mm - see
picture) to tighten the compressed air cylinder, turn the diaphragm with a screwdriver
to the necessary position according to the following picture.
To reassemble the valve head, fix it carefully with the Allen screw.
Turn the adjusting screw back in when the valve is assembled.
After the valve has been completely assembled, turn the adjusting screw back in again.

Note:
The scale may no longer show exactly„0“. In this case, calculate the setting
relative to the closed position. This will not affect the operation.
