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. 2 3 4 1 5 6 Figure 2.0 4 11. TROUBLESHOOTING PROBLEM POSSIBLE CAUSE Fluid pressure too low CORRECTION Increase fluid pressure No fluid flow Operating pressure too low Dispense tip clogged or damaged Increase air pressure to 70 psi (4.8bar) Replace tip Fluid cured in valve chamber Clean valve thoroughly Fluid pressure fluctuating Make sure fluid pressure is constant Inconsistent fluid flow Valve operating pressure is too low Increased valve pressure to 70 psi (4.8bar) Check to make sure the valve Valve open time is not consistent controller is providing a consistent output Air trapped in fluid housing Purge valve Fluid drools after the valve closes, eventually stopping Air trapped in fluid housing Purge valve Lower seal damaged or worn Replace lower seal Steady drip Spool damaged Inlet air fitting is too long, pushing the spool opened Replace spool Replace air fitting Valve re-assembled incorrectly Re-assemble valve, follow reassembly instructions 13 10.

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 3 1 2 4 Figure 3.0 5 6. TYPICAL SYSTEM SET-UP 9.
