Tridak now offers the Model
340PS and the Model 340PSL positive-displacement dispensing valves for accurate
and repeatable fluid dispensing. Both
valves offer true positive-displacement operation and incorporate the
efficiency of a disposable fluid path from the reservoir to the dispense tip.
Sequenced piston actuation within the Model 340 series valves dispenses a
consistent shot-to-shot volume regardless of material viscosity or viscosity
fluctuation. This performance feature is accentuated in applications that
require extremely precise dispense volume repetition. The Model 340
positive-displacement valves are effective with materials that are shear
sensitive, extremely high or low in viscosity, possess tacky or stringy
characteristics, or have drifting viscosities due to limited pot life.
The Model 340 Series
dispensing valves are available in two basic models, the 340PS and the 340PSL.
The 340PS is best suited for smaller shot volumes, from 0.004 mL to 0.180 mL
shots. The 340PSL offers larger shot size capability, up to 1.200 mL. Both
valves are available with polyurethane, flexible polyethylene, or
This series of valves features patented over-stroke adjustment, which prevents
premature tubing wear, allowing users to secure millions of cycles before
tubing replacement may be required. Tridak offers a range of tubing materials,
including FDA-approved materials for medical, pharmaceutical, or food contact
applications. Tridak Applications Engineering should be contacted to determine
a tubing material that is best suited for an application.
