MicroMark Spray Marking Valve Systems

Nordson EFD’s unique MicroMark™ spray marking systems eliminate clogging, maintenance, and downtime by using a programmable air delay after each cycle to clean the spray nozzle.

Ideal for color coding, indicating pass/fail, or showing production or test status, our marking systems produce round patterns and stripes from 5.0 mm (0.20”) to 30.4 mm (1.20”) wide without overspray.

The valves can be activated manually, or interfaced with other systems to mark at scheduled intervals or whenever a signal is received.
