Nordson EFD provides a complete line of modular metal valves that can be easily
disassembled and cleaned after mixing. Maintaining valves that handle reactive
resins can be time-consuming and expensive — a plugged valve translates to lost
production, and even a partially plugged mixer results in poor quality.
With meter mix and dispense systems, the pneumatic Series 400 Autovalve is a
durable and reliable valve. The A and B shut-off pistons have PTFE seals allowing high
ow with minimal maintenance as these seals can be adjusted without disassembly of
the valve body. The 9/16-18 uid inlet ports of the Series 400 Autovalve allows ow
rates of 3-4 gallons per minute, depending on pump capability and material viscosity.

Series 400HF Autovalve
The 400HF Valve provides ow rates that are 15-30% greater than the standard 400
Valve conguration, without compromising accuracy or consistency. The large 3/4"
material inlet ports permit ow rates of 4-5 gallons per minute, depending on pump
capability and material viscosity.

Series 450 Autovalve
The pneumatic Series 450 Autovalve is similar to the Series 400 Autovalve, except
for the shut-off pistons which ensure good control of dot or shot volume. After each
shot, the dual pistons retract and “snuff back” material from the end of the mixing
nozzle. This feature helps eliminate “after drool.” This valve includes hard-coated and
lubricated pistons. It can be used either as a stationary head or hand-held unit. In
addition, seals can be adjusted without disassembly of the valve body.

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. Recirculation occurring at the valve instead of
the pump eliminates pressure buildup in the lines, preventing off-ratio dispensing.
This innovative dispense valve is designed
specically 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.
