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.

Theory of operation

The TS5420 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.

5. Set Up Instructions
Refer to Figure 3.0
Note: This installation uses luer lock adapters shipped with the valve. Any
approved material line with 1/8" NPT connections will work.
•
If desired, mount the valve to the bracket included.
•
Connect fluid feed line to valve inlet port (1).
•
Install valve actuating air hose to air inlet port (2)
•
Connect valve air hose to an approved valve controller.
•
Set the fluid reservoir pressure. Do not exceed 300 psi (7 bars)
•
Make sure all connections are tight.
•
Place container under the valve outlet and activate the valve until the fluid
flows steady.
•
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
•
Dispensing tip size
