Our blow-through rotary valve is suitable for powdery and finely grained bulk materials. Please specify the range of grain sizes when making your enquiry. The bulk material must have good conveying and flow properties. Because both the rotors and housings are precision-finished to the narrowest tolerances, the blow-through rotary valve made by Barl feature the highest possible degree of sealing integrity. The flushing air connections are as standard as the Venting purging and the external bearing.
The blow-through rotary valve are naturally also available in both pressure-shock-proof and flame-propagation-proof design.
