2. UNPACKING AND INSPECTION

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

These will include:

• Valve assembly

• Valve bracket and air hose

• Sample tip kit and fluid line

• User guide

3. DESCRIPTION

The TS5322 Series Mini Spool Valve is designed to dispense medium to high

viscosity fluids with very precise deposits, over a wide range of shot and bead

sizes. An internal spring return makes the valve fully adaptable for use with any

time/pressure controller. A short opening stroke provides extremely fast, positive

shut-off. An external adjustment makes it easy to fine tune “suck-back” level. The

TS5322’s compact design allows for mounting flexibility and easy integration into

automated applications.

4. THEORY OF OPERATION

The TS5322 Series Mini Spool Valve is a normally closed spool valve with

adjustable “suck-back”. Input air pressure of 70 psi (4.8bar) through port (1)

drives the spool assembly (2) forward, opening the material path from the material

inlet (3) to the material outlet (4). Relieving the input air pressure allows the spool

assembly to travel back to the closing position, ensuring rapid “fail-safe” shut-off

of fluid flow

An oil chamber (5) is provided above the upper seal to create an additional liquid

seal that will prevent moisture from being carried on the spool. The auxiliary air

inlet port (6) is provided so that the valve may be connected for air closing with or

without the spring.

PROBLEM POSSIBLE CAUSE CORRECTION

No fluid

flow

Fluid pressure too low Increase fluid pressure

Operating pressure too low

Increase air pressure to 70 psi

(4.8bar)

Dispense tip clogged or

damaged

Replace tip

Fluid cured in valve chamber Clean valve thoroughly

Inconsistent

fluid flow

Fluid pressure fluctuating

Make sure fluid pressure is

constant

Valve operating pressure is too

low

Increased valve pressure to 70 psi

(4.8bar)

Valve open time is not consistent

Check to make sure the valve

controller is providing a

consistent output

Air trapped in fluid housing Purge valve

Fluid drools

after the

valve closes,

stopping

Air trapped in fluid housing Purge valve

Steady drip

Lower seal damaged or worn Replace lower seal

Spool damaged Replace spool

Inlet air fitting is too long,

pushing the spool opened

Replace air fitting

Valve re-assembled incorrectly

Re-assemble valve, follow re-

assembly instructions

5. SET-UP INSTRUCTIONS

1. Connect the fluid reservoir feed tube (1) to the valve inlet port (2).

2. Connect the valve air hose (3) to the valve controller or other pneumatic device,

which is used to control the valve.

3. Connect an appropriate nozzle or dispensing tip (4) to the fluid outlet port.

4. Set the valve controller pressure at 70 psi (4.8bar).

5. Set the fluid reservoir pressure. Do not exceed 500 psi (34.5bar). For TS5322D,

do not exceed 100 psi (6.9bar).

6. Ensure all connections are tight.

7. Place container under the valve outlet and activate the valve until the fluid

flows steady.

The amount of fluid that flows through the valve is determined by:

• Valve open time

• Fluid reservoir pressure

• Dispensing tip size
