Model 340PS and 340PSL positive-displacement dispensing valves for fluid dispensing incorporate the efficiency of a disposable fluid path from the reservoir to the dispense tip. Sequenced piston actuation dispenses a consistent shot-to-shot volume. 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. 340PS is suited for shot volumes from 0.004 to 0.180 mL. 340PSL offers shot size capability up to 1.200 mL. Both are available with polyurethane, flexible polyethylene or Teflon tubing.
