Introduction

To obtain Maximum performance of this valve, please read and follow these instructions

carefully before operating.

Receiving Inspection Procedures

Carefully unpack the valve and examine the items contained in the carton.

These will include:

- Valve assembly

- Accessory Pack consisting of:

- Sample Needle Kit

- Sample Fluid Line

Inspect the valve for any damage that might have occurred in transit. If such damage

has occurred, notify the carrier immediately. Claims for damage must be made by the

consignee to the carrier and should be reported to the manufacturer.

Product Description

The DV-5325 Adjustable Mini Spool Valve is designed to dispense medium to high viscos-

ity material with very precise deposits over a wide range of shot and bead sizes down to

a fraction of a micro liter. An internal spring return makes the valve fully adaptable for use

VC-1000 time/pressure controllers. A short opening stroke provides extremely fast, positive

shut-off. An external adjustment makes it easy for the operator to fine tune“Suck-Back”. The

DV-5325’s compact design allows for mounting flexibility and easy integration into auto-

mated applications.

OPERATING MANUAL DV-5325

OPERATION

Valve Operation

The DV-5325 is a normally closed spool valve with

adjustable suck-back. Air pressure through port (1)

drives the spool assembly (2) forward opening the

material path from the material inlet (3) to the material

outlet (4). Return air (5) or return spring (6) reverses

the spool assembly travel to close the material path.

An oil cup (7) provides a moisture barrier for the seal

when dispensing a moisture sensitive material.

Typical Dispense Performance

Minimum Shot Size (water): = .002 ml

Flow Rate at 100 PSI (water): = 2700 ml/min

Operating Frequency: = 700 cycles/min

Material Viscosity Range: = Up to 1 Million CPS

Repeatability: = ±0.2%

Set-Up

Refer to illustration.

Note: This installation uses Luer Lock adapters shipped with the valve. Any

approved material line with 1/8“ N.P.T. connections will work.

1. If desired, mount the valve to the bracket included (8).

2. Connect material feed line to inlet port (3). Valve segment with inlet port can be rotated

up to 360° to provide repositioning of inlet port. Caution: Do not turn inlet

port far enough to disconnect from Air Cylinder.

3. Connect valve actuating air line to valve port (1 ) and to an approved valve

controller.

4. Pressurize material reservoir (Material pressure not to exceed 500 PSI).

5. Activate the valve until all air has been purged from Material Line. It may be helpful to

turn the valve upside down to purge air.

6. Attach desired dispense tip to the outlet Luer Lock adapter.

OPERATING MANUAL DV-5325

Valve Adjustment

Shot size and bead width are dependent on the following factors:

1. Length of actuation, set at controller (Valve open time).

2. Material supply pressure at reservoir.

3. Material viscosity.

4. Dispense tip size.

Suck-Back Adjustment

The DV-5325 Mini Spool Valve is equipped with a natural“suck-back” feature. When

closing, the valve will pull, or “suck-back” material into the material chamber thus

helping to prevent dripping. It is possible to adjust the amount of “suck-back” by turning

the adjustment knob on the back of the valve.

Note: There are two notches in the adjustment cap that mark the maximum and minimum

“suck-back” settings. Turning the adjustment knob into the valve past the minimum

mark will cause the valve to remain open. (see illustration below).

MAINTENANCE

Cleaning and Seal Replacement

Disassembly

(refer to diagram on page 10)

Tools Required O-ring removal tool (P/N TSD1597-7) and Retaining Ring Pliers

with 0.053” tip.

Caution: Disconnect all material and air pressure lines before performing any mainte-

nance on this valve.

Note: To prevent possible damage to seal components, following these instructions

in the following sequence is recommended. Refer to diagram on

page 10.

1. Remove all hoses and fittings from Valve Body (6).

2. Unscrew the End Cap (17). Remove retaining ring (24) and remove the Spring (11).

Carefully remove the Spool Assembly (12) by pulling straight out.

3. Hold the Valve Body (6) and rotate the Air Cylinder (15) counterclockwise. When com-

pletely un-threaded, pull the two valve segments straight apart to separate.

4. Using Retaining Ring Pliers, remove Retaining Ring (22). Remove Stainles Steel Washer

(5) from valve body.

5. Note orientation of the Seal (4) in Valve Body (6) prior to removal. Remove Seal.

6. Remove four [4] Socket Cap Screws (2) in Outlet Block (1) and separate Outlet Block (1)

from Valve Body (6).

7. Note orientation of Seal (4) in outlet block (1) and remove.

8. Clean and inspect Spool (12), Seal surface and Seals (4, 4 & 5) for wear and damage.

Replace parts as necessary.

TROUBLESHOOTING

Problem Check & Correction

No Material Flow • Material pressure too low - Increase material pres

sure.

• Operating air pressure too low - Increase air pressure

to 50 PSI.

• Material cure clogged in valve - Clean Valve

Inconsistent Material Flow • Inconsistant operating air pressure

• Inconsistant material pressure

• Operating air pressure too low - Increase air pressure

to 50 PSI.

• Air trapped in fluid housing - Purge Valve

• Length of actuation too short - Increase shot time

Material continues to flow after

the valve is closed, but eventu-

ally stops.

• Air trapped in material line or fluid housing - Purge

Valve

Steady Drip • Suck Back Cap fully closed - Unscrew cap until drip-

ping stops

• Damaged spool and/or seals - Replace worn or dam-

aged parts

• Material pressure exceeds 500 PSI - Lower Material

Pressure

• Valve reassembled incorrectly after cleaning -

Reassemble following instructions

• Actuating air pressure not properly exhausted -

Check pneumatic circuit

• Return spring missing or damaged - Replace spring.
