5.4 Valve Types
Compatible with the MDC 3500 are valves of the following series.
• MDV 3580 (low to high viscosity; top adjust with bayonet fastening)
• MDV 3581 (low to high viscosity; top adjust with bayonet fastening)
• MDV 3583 (low to high viscosity; top adjust with bayonet fastening. You will need the
additional manual Quick Reference Guide MDV 3583.)
• MDV 3583-FH (low to high viscosity; top adjust with bayonet fastening and frame heater. You
will need the additional manual Quick Reference Guide MDV 3583.)
Which type is best suited for your application? This depends on different criteria. Air cooled
valves should be your choice, if you dispense with lots of power or if you use a nozzle heater and
constant temperatures are important.
