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 TS5420 Needle Valve is designed to dispense low to medium viscosity 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 with Techcon Systems time/pressure controllers. A short opening stroke provides extremely fast, positive shut-off. An external stroke control adjustment makes it easy for the operator to fine tune shot sizes. The TS5420's compact design allows for mounting flexibility and easy integration into automated applications. 4. THEORY OF OPERATION The TS5420 Needle Valve is a normally closed, adjustable opening, needle and seat valve. Inlet air pressure through port (1) retracts the needle assembly (2) from the seat (3) allowing fluid to flow from the valve fluid inlet (4) to the Luer lock outlet (5). Relieving the input air pressure allows the spring (6) to return the needle back to its position to close the material path. 3 4 6 1 5 2 Figure 2.0 11. TROUBLE SHOOTING PROBLEM No fluid flow Inconsistent fluid flow POSSIBLE CAUSE Fluid pressure too low Operating pressure too low Dispense tip clogged or damaged CORRECTION Increase fluid pressure Increase air pressure to 70 psi (4.8bar) Replace tip Fluid cured in valve chamber The stroke adjustment closed Fluid pressure fluctuating Clean valve thoroughly Open stroke adjustment counterclockwise Make sure fluid pressure is constant Valve operating pressure is too low Valve open time is not consistent Increased valve pressure to 70 psi (4.8bar) 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, eventually stopping Air trapped in fluid housing Purge valve Steady drip Dirty needle and seat Worn needle and seat Fluid pressure exceeds 300 psi (20.7bar) Valve re-assembled incorrectly Perform thorough cleaning Replace worn or damaged part Lower fluid pressure Re-assemble valve follow instructions 4 13 10.

SETUP INSTRUCTIONS Refer to Figure 3.0 Note: This installation uses Luer lock adapters shipped with the valve. Any approved material line with '' NPT connections will work. 1) If desired, mount the valve to the bracket included. 2) Connect fluid feed line to valve inlet port (1). 3) Install valve actuating air hose to air inlet port (2). 4) Connect valve air hose to an approved valve controller, such as the TS500R. 5) Set the fluid reservoir pressure. Do not exceed 300 psi (20.7bar). 6) Make sure all connections are tight. 7) Place a container under the valve outlet and activate the valve until the fluid flows steady. 8) Attach appropriate dispense tip to the Luer lock outlet fitting (3). The amount of fluid that flows through the valve is determined by: · Flow control adjustment: Turn end cap counterclockwise to increase material flow rate. · Length of actuation, set at controller (valve open time). · Fluid reservoir pressure · Dispense tip size 1 2 Figure 3.0 3 5 6.

MAINTENANCE AND CLEANING: Tool required: 5/8'' open-end wrench; Snap ring pliers, o-ring removal tool (P/N TSD1597-7). Normally, purging the valve with appropriate flush material or solvent after use is sufficient for cleaning. However some material may cause a buildup 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: 5420-SEALKIT · To repair valve, please order valve kit part number: 5420-VALVEKIT 7.1 Thorough Cleaning Refer to figure 5.0 1.

Secure the nozzle in a "soft jaw" vise and then pull the thumb screw, with the seat attached, straight out. 3. Install the new seat on the thumb screw and then insert the thumb crew straight into the nozzle. To ensure proper seat alignment, it is recommended that the seat installation is done on an Arbor Press. 7 7.3 To Replace Seal in Air Cylinder 1. Hold the fluid housing (8) and rotate the air cylinder (2) counterclockwise. When completely un-threaded, pull the two valve segments straight apart to separate. 2.
