Company: Coperion


Equipment Snapshot: The Coperion ZRD Hygienic (Heavy-Duty Premium) rotary valve is especially designed for sanitary food applications where contamination is a constant concern and frequent disassembly and cleaning is required. 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]. The valve has an explosion pressure shock proof rating of 10 bar(g) [145 psi(g)].

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.
