Product Data Sheet
TS5420 Series
Needle Valve
The TS5420 Series Needle Valve is a normally closed needle
and seat dispensing valve, which is designed to dispense low medium viscosity fluids. TS5420 Series can dispense very
precise deposits over a wide range of deposit sizes. The
TS5420 Series is a pneumatically triggered single-acting valve
that can be used with an internal spring close (single action) or
may be connected for air closing without the spring (double
acting).

KEY FEATURES AND BENEFITS

Low maintenance design
Rotating tip allows for easy tip integration
Can handle fluid pressures up to 300 psi
(20.7bar)

The internal spring return makes the valve fully adaptable with
Techcon Systems controllers. A short opening stroke provides
extremely fast, positive shut-off and the external stroke control
adjustment allows the operator to fine tune deposit sizes. Air
pressure through the air inlet port retracts the needle assembly
from the seat allowing fluid to flow from the valve fluid inlet to
the Luer lock outlet. Relieving the input air pressure allows the
spring to return the needle back to its position, to close the fluid
path, ready for the next dispensing cycle.

The valve is shipped with the following items:

Mounting bracket kit
Valve air hose
Luer lock fluid line
Fluid inlet fittings - 1/4'' compression and Luer lock type
Dispensing tip selection pack

TYPICAL APPLICATIONS

Applying lubricant in Automotive electrical switches
Dispensing UV beads in LCD bonding applications
Impregnating humidity indicator cards (HIC) with fluid
chemical in semiconductor packaging applications
