Type RS (EX) rotary valve

Dosing and drop through rotary valve, particularly for dosing powders and granulates from silo’s or bunkers. It has a rectangular in- and outlet, which makes this valve perfect as inlet valve in pneumatic lines, even with abrasive media. This valve has got a large range of different characteristics to choose from and is also available for big capacities, which allows you to choose the best version to suit your demands.
