Our rotary valves are suitable for powdery and finely grained bulk materials. Please specify the range of grain sizes when making your enquiry. For reasons of operational reliability, this type of valve is especially recommended if the bulk material is one that has a tendency towards coating formation. The bulk material must have good conveying and flow properties. Because both the rotors and housings are precision-finished to the narrowest tolerances, the rotary valves made by Barl feature the highest possible degree of sealing integrity.
The cleaning covers integrated as a standard feature ensure quick and easy cleaning. How all other rotary valves made by Barl Maschinenbau GmbH the external roller bearings of the self-cleaning rotary valve are also set at a distance from housing.
The rotary valves are naturally also available in both pressure-shock-proof and flame-propagation-proof design.
