Piston dispensing valve 450 series

precision

The Series 450 Autovalve is a tough and dependable pneumatic valve that comes with meter mix dispensing systems. Aside from that, dismantling its body is not required when adjusting the seals. The shut-off pistons assure the accurate control of dot and shot volume, which is an upgrade from the Series 400 Autovalve. Following each shot, the dual pistons returns to its original position, and absorbs the material back from the element mixing nozzle. This add-on eliminates drips and smudges. It contains hard-coated and lubricated pistons, and can also be used not only as a hand-held unit but also as a stationary head. Some optional features include stainless steel valve, a night cap ratio checkup, and Polytuff, PTFE, Viton® and EP Seals.
