OVERVIEW OF MICRO VALVE SMLD CONFIGURATION AND VARIANTS

ORDERING MATRIX MICRO VALVES

1. BASIC VALVE TYPEUsageSMLD 300SMLD 300G
SMLD 300

4. NOZZLE DIAMETERUsageSMLD 300SMLD 300G
The nozzle diameter and valve travel are important influential parameters for drop formation and the dispensing volume. Depending on the desired dispensing result, corresponding combinations can be selected.Ø 0,10 mmØ 0,10 mm
Ø 0,15 mmØ 0,15 mm
Ø 0,20 mmØ 0,20 mm
Ø 0,30 mm
Ø 0,45 mm
Ø 0,60 mm
4. VALVE TRAVELUsageSMLD 300SMLD 300G
The valve travel (stroke) defines how much the ball lifts out of the seat at the opening. The valve travel together with the nozzle diameter has a great influence on the drop formation and dispensing quantity.
Common and proven combinations:
Ø 0.1 / 0.03 or 0.06 travel
Ø 0.15 / 0.03 or 0.06 travel
Ø 0.2 / 0.06 or 0.1 travel
Ø 0.3 / 0.1 travel
Ø 0.6 / 0.15 travel
