Hygienic rotary valves
USDA approved following certification in compliance with the USDA Dairy Grading Branch, Coperian hygienic ZRD discharge valves and ZXD blow-through valves are designed for applications involving frequent changeovers from one product to another, for the processing of products with adhesive tendencies, in pneumatic conveying systems and for the discharge of powdered and granular materials. The smooth-surfaced rotary valves have no dead spots and are manufactured completely in stainless steel. They are fitted with FDA-compliant sealing materials as standard. Slots and gaps have been reduced; unavoidable slots and/or gaps are flush-sealed, both on the inside and outside of the valves.
