400 Series Autovalves
With meter mix and dispense systems, the pneumatic
series 400Autovalve is a durable and reliable valve. The A
and B shut off pistons have Teflon seals allowing high flow
with minimal maintenance. In addition, the seals can be
adjusted without disassembly of the valve body.

450RC Series Snuff Back Autovalves
The pneumatic Series 450RC Re-Circulating Snuff Back
Autovalve is similar to the 400 Series, except for the
shut-off pistons. The 450 ensures 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.
