A company distributing Akzo Nobel powder, and powder coating application machines are using AKO Pinch Valves of the VMP plastic type on the equipment. They are using pinch valves because they do not get any pulsing of the powder with them, and there is also a reduction in air consumption with the pinch valve.

This particular plastic pinch valve has white POM body, but is also available in black. The VMP pinch valve product range comes in sizes DN10-50.
