Hygienic Design

The ZFD rotary valve is engineered with a strict focus on hygienic design, making it ideal for processes where cleanliness and product safety are paramount. Built as a blow-through valve in full CIP execution, it allows automatic wet cleaning without any need to open the valve, ensuring fast and repeatable sanitation. CIP (Cleaning-in-Place) enables the entire cleaning cycle, including rinsing, washing, and sanitizing, to be carried out automatically within the installed system. This eliminates manual disassembly, reduces downtime, and ensures consistent, validated cleaning results.
