The 450RC Autovalve allows continuous ow of material while still being able to
control shut-off at the mixer. Typical uses are for heated materials or materials with
llers that need to remain suspended. Gear pump applications can also benet
because pumps can be kept running while material is shut off at the mixer.
Recirculation occurring at the valve instead of the pump eliminates pressure buildup
in the lines, preventing off-ratio dispensing. The valve also incorporates a snuff-back
feature that minimizes or eliminates the possibility of material dripping or stringing
when the valve shuts off.

Recommended Mixer:
Series 160 Mixer
This innovative dispense valve is designed specically for two-component urethanes and
eliminates exposure of wetted shafts to air. Since 2K urethanes are moisture sensitive,
any contact with air can cure the material, locking up the dispense valve.

DISPENSING TIPS FOR MIXERS
Luer Lok adapters (locking hubs) are used for
attaching Optimum dispensing tips to Series 190 and
160 mixers. If you want to use a metal jacket with the
3.16” ID or 1/4” ID bell mixers, order the mixer and the
Luer Lok fitting as two separate items unassembled:
square hub outlet and #7700943 Luer Lok fitting (bag
of 50). See Optimum Dispensing Tips for details:

BLOCK MANIFOLDS FOR MIXERS
Nordson EFD’s two-component manifolds separately port the resin and
hardener into the mixing nozzle. Cleanup simply involves wiping the
manifold face after the nozzle has been removed. To prevent back flow
or cross contamination of reactive material, inline check valves are
available. Designed when you’re dispensing without a meter mix valve,
but directly through the mixer. For use with Series 160 and 162A.
