Inspecting the DJ-100 for Wear
Before start of production, the DJ-100 ceramic ball, valve seat, sealing valve body / rod (white o-ring), &
rod should be inspected to ensure all particulate and any cured fluid is properly removed. It is critical to
the lifetime of the DJ-100 assembly to remove cured fluid, debris or any particulate from the mating
surfaces between ball tip and valve seat. Failure to properly clean & remove all particulate from these
mating surfaces can cause poor dispense quality and will shorten the lifetime of the DJ-100. The ball tip
and valve seat cannot be replaced, and must be maintained to the highest level of accuracy. Asymtek
recommendeds that you inspect the valve seat using a laboratory microscope (10-30 x magnificatioin) to
ensure all particulate is removed before start of production.
WARNING! Do not use sharp or pointed metallic tools, as they can scratch the mating
surfaces and cause poor jetting performance and leaking. Cleaning swabs are
included in Kit P/N 7218366.
Jet Replacement Program
Asymtek offers a Jet Replacement Program available during the first two years from the original ship date
of the DJ-100. If the ball & seat wear out due to normal operation & use, Asymtek will offer a replacement
jet. Please contact your local service or sales team for details on the replacement jet program.
