Pinch valve, flange, DN50, Aluminium (ALU), 0-6 bar

Field of application: 
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: 
Housing: Aluminium, flange: Cast aluminium with bushing of 1.4404 (parts in contact with media from 1.4404), sleeve: natural rubber, food safe quality 

Control pressure: 
max. 1,5 to 2 bar higher than the medium's pressure 

Temperature range: 
-10°C to max. +80°C 

Optional: 
Natural rubber sleeve, abrasion resistant (-10°C to max. +80°C) -AB, EPDM sleeve (-10°C to max. +90°C)* -EP, aluminium flange and NBR sleeve (economical version) -B

*DN 40 - DN 50: -10°C to max. +120°C, **Please enter the required material: LE = natural rubber, food quality, AB = natural rubber, abrasion proof, EP = EPDM, ***steel housing and flange
