Diaphragm Vavles

TS5624DMP Disposable Material

Path Diaphragm Valve

The TS5624 Disposable Diaphragm Valve features a “first to market”

Disposable Material Path. Difficult fluids such as CA’s and pre-mixed 2-part

epoxies, can now be dispensed without the need of frequent cleaning, by

simply replacing the entire wetted area in a matter of seconds, while the

valve stays on the production line.

The wetted parts are manufactured from black Polyethylene to prevent

moisture and UV light come into contact with the dispense fluids. As a result,

moisture sensitive fluids such as Cyanoacrylate and UV cured adhesives can

be dispensed reliably and accurately.

The TS5624 dispenses low to medium viscosity fluids over a wide range of

shot and bead sizes, down to a fraction of a micro liter. An internal spring

return makes the valves fully adaptable for use with Techcon Systems

controllers. A short opening stroke provides an extremely fast and positive

shut-off.

The seal-less valve design offers an excellent moisture sensitive resistance

and the incorporated diaphragm creates a barrier between the wetted parts

and the air cylinder.

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.
