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.

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

7. MAINTENANCE AND CLEANING:
Tool required: O-ring removal tool (P/N TSD1597-7), snap ring pliers.
Normally, purging the valve with appropriate flushing material, or solvent after
use is sufficient for cleaning. However, some material may cause a build-up in the
valve chamber, in this case periodic and thorough cleaning will be required.
NOTE:
•Make sure the fluid pressure is released before valve is disassembled.
•To replace seals please order seal kit part number: 5322-SEALKIT.
•To repair valve please order valve kit part number: 5322VALVEKIT.
