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.

MANIFOLDS FOR SERIES 400 AUTOVALVES
Ratio Part # (Manifold) Part # (Manifold with solvent port) Material Flow
1:1 7701933 7701935 Aluminum Low Flow
1:1 7701942 - Aluminum High Flow
Wide 7701946 - Aluminum High Flow
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
Recommended Mixer:
Series 160 Mixer
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.

Series 160 Mixer
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 benet
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.

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.
