Meter Mix Valves
Recommended Mixer:
Series 162A Mixer
Series 400HF Autovalve
The 400HF Valve provides ow rates that are 15-30% greater than the standard 400
Valve conguration, 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.

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. 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
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.
