2. UNPACKING AND INSPECTION
Carefully unpack the valve and examine the items contained in the carton.
These will include:
• Valve Assembly
• Valve bracket
• Sample Needle Kit and fluid line
• Valve Air Hose
• User guide
3. DESCRIPTION
The TS5440 Microshot 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- o ff. An external stroke control adjustment
makes it easy for the operator to fine tune shot sizes. The TS5440’s compact design allows for
mounting flexibility and easy integration into automated applications.
4. THEORY OF OPERATION
The TS5440 is a normally closed, adjustable opening, needle and seat valve. Inlet air pressure through
port (1) retracts the needle assembly (2) from the seat inside the dispensing tip (3) allowing material to
flow from the valve material inlet (4) to the dispensing tip (5). Relieving the input air pressure allows
the spring (6) to return the needle back to its position to close the material path.
