1 Dispense Valve Selection Guide

2 Choosing the right dispense valve for an application starts with the fluid. ALICATION DEFINITIONS Use this guide to: See which Nordson EFD valves work with specific fluids and applications Compare the features of EFD valves and controllers Select a type of fluid for an application Microdots Any deposit having a volume less than µl. ( µl = microliters = /1 cc). Dots Any deposit having a volume larger than µl. Jetting Applying microdots, dots, lines, stripes, and encapsulates without making contact with a surface - also called non-contact dispensing. For example, if you know you want to use a jet dispensing valve because of its significant precision and fast cycle rate, you could use this guide to identify the types of fluids most suitable for jetting. Benefits erformance that s proven for millions of dispense cycles otting Filling a cavity usually containing an electronic device, electronic circuit or wires. Encapsulating Applying a coating to an electronic component for protection from mechanical or environmental damage. Lines/Stripes A line, bead or stripe of material. Long service life with minimal maintenance Worldwide technical assistance Global application testing labs lease note this guide does not include every EFD dispensing solution available. It s important to speak with an experienced EFD application specialist when choosing the right solution for your application. Filling/ackaging Filling containers such as small bottles, cartridges and tubes. Microspray Narrow spray pattern capability as small as 1 mm (.4 ) wide. Applying fluids using low pressure air to break the fluid into fine droplets for coating or marking. Internal ing the inside diameter of holes and cylinders.

Maximum operating temperatures of EFD valves should not exceed 43 C (11 F) except for the 736HA-NV, 741V, 781S, and Series valves, which can operate up to 11 C (21 F). 2
