Model 340 Series: Positive-Displacement Valves
with Disposable Fluid Path Technology
Tridak's Model 340 Series dispensing valves offer true positive-displacement operation with the efficiency of disposable fluid path technology. Sequenced piston actuation within the Model 340 valve dispenses a consistent volume of fluid 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 extremely high or low in viscosity, possess 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 urethane tubing, flex-PE, or Teflon®. Consult with Tridak Applications Engineering to determine a tubing material that is best suited for your application. With minor modification, these dispensing valves can be gang mounted for multi-component dispensing.
The Model 340 Series positive-displacement valves must be actuated with a Tridak 340 valve controller. This controller is specifically programmed to initiate the proper piston sequencing to produce positive-displacement dispensing.
