Operating range:
Pneumatic pinch valves are the fitting solution for the shut-off, regulation and dosing of abrasive, corrosive and fibrous products. They are ideally suited for use with these products due to their completely free product flow, whereby a practical blocking and dead space-free fitting results. The pneumatic pinch valves ensure an optimal shut-off, also when used with solids, such as granules, powders, pellets, chipping, sand, cement, gravel, textile fibres, carbon, fine glass fragments and liquids that contain solids.
Advantages:
•Completely free flow,
•No clogging by media,
•Minimum frictional resistance,
•Quick opening and closing,
•Low energy consumption
Materials:
Body: aluminium, flange: cast aluminium with bushing made of 1.4404 (wetted parts made of 1.4404), cuff: natural rubber in food quality
Control pressure:
max. 1,5 to 2 bar higher than the medium's pressure
Temperature range:
-10°C to max. +80°C
