Needle Valves

TS5400 Series Needle Valves

Needle Valves dispense very precise deposits over a wide range of shot

and bead sizes due to a minimal dead fluid zone. An external stroke

control adjustment to fine-tune shot sizes. Easy to maintain, with little or

no downtime. The compact design and easy-mount threaded hole allows

for easy integration into automated applications.

The TS5420 Adjustable Needle Valve is a pneumatically triggered single-

acting valve that can be used with an integral spring close (single action)

or may be connected for air closing without the spring (double acting).

The TS5440 Microshot Needle Valve, with its needle closing the fluid path

directly on the cannula inside the dispensing tip hub, can dispense very

precise deposits down to 0.0005 cm

Key Features:

• Precise and consistent shot sizes

• Adjustable flow control

• Zero dead fluid zone

• Simple and low maintenance design

Typical Applications:

To dispense microdots of low viscosity fluids such as: solvents, inks, oils,

activators, primers; the TS5440 is excellent to dispense microdots of UV

adhesive used in medical device manufacturing.

Spool Valves

TS941 High Pressure Spool Valve

The Spool Valves provide precise shot accuracy along with “high volume”

capacity over a range of material viscosities, shot sizes and pressures.

They feature “suck back” anti-drip as well as a fast on/off dispensing

function that is not affected by material input pressure. An optional oil

chamber creates an additional liquid seal to prevent moisture from being

carried on the spool, excellent for moisture sensitive materials.

Pneumatically activated, the valves can be used with an internal spring

close (single acting) or an air-closing connection (double acting).

Output is a

1/4" NPT which allows multiple types of tips to be used.

TS5322 Mini Spool Valve

The Mini Spool Valve Series is designed for better accuracy with lower

pressure. The series operates similar to the TS941, however, it is smaller

in size.

Typical Applications:

Suitable for moisture sensitive adhesive when utilizing supplied oiler. The

Spool Valves can be used in a wide range of applications such as flux

paste, grease, RTV Silicone, UV cure gel, solder mask, gasketing.

Pinch Tube Valves

TS1212

Pneumatic Pinch Tube Valve

Provides control for continuous or micro shot applications of low to

semi-viscous fluids. The “ON/OFF” control is achieved by

automatically opening and closing (pinching) a molded polyethylene

tube assembly. Adjusting the opening size of the pinch tube

assembly determines the shot size or flow rate. In addition, the air

actuated valve can be timed to develop desired shot sizes. Finally, a

wide range of dispensing tips can be used to further refine the amount

of dispensed output. The only part of the valve making contact with

the fluid being dispensed is the disposable pinch tube assembly.

Replacement pinch tube assemblies are sold in packages of 10.

Key Features:

• Disposable fluid path

• Simple to operate

• Compact size and weight

Typical Applications:

Cyanoacrylates, anaerobics, two-part adhesive, etc.
