The “UPR” rotary valve is particularly suitable for the metering and pneumatic conveying of granular, flaky or ground products.Thanks to its sturdy construction and flanging unified according to UNI PN10 standards (DIN2576 ND10) it is suitable for use in both heavy industry and in the chemical and plastic industrial fields.The special conformation of the inlet and a series of other technical adaptations reduce the risk of the jamming of the product between the blade and the stator if difficult products need to be discharged.The external bearings and the packing gland system with PTFE sealing provide further guarantees of rational performance and also make possible to use the valve at high temperatures without any change but tolerances.
