Series 450 Autovalve

With meter, mix and fluid dispensing systems, the Series 450 Autovalve is a durable and reliable pneumatic valve. In addition, the seals can be adjusted without disassembly of the valve body.
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 element mixing nozzle. This feature helps eliminate "after drool." This pneumatic auto valve includes hard-coated and lubricated pistons. The Series 450 Autovalve can be used either as a stationary head or hand-held unit.
