This 3-D animation demonstrates Coperion’s ZRD Hygienic rotary valve. The rotary airlock is designed for sanitary, pharmaceutical, food and chemical applications where contamination is a concern, and frequent cleaning is required.
The ZRD Hygienic includes full access extraction system and a large inlet for high filling efficiency. Without removing the valve from the system, the ZRD Hygienic can be easily disassembled, cleaned and reassembled. The full access extraction system fully supports the rotor as it is removed for cleaning, making it an ideal method for facilitating endplate and rotor removal. The entire unit is specially designed to avoid contamination with product contact surfaces constructed from DIN 1.4404 [AISI 316L] stainless steel. The ZRD Hygienic is designed according to EHEDG guidelines with pressure differentials up to 1.5 bar(g) [21 psi(g)] and temperatures up to 100° C [212° F].
