Electric Operated Zero Bacteria Valve
Electric Operated Zero Bacteria Valve - 1257 and 1357 series
SUDE Electric Operated Zero Bacteria Valves are precision-engineered hygienic valves designed to ensure contamination-free, sterile, and reliable flow control in critical process industries. Built with crevice-free internal geometry, full drainability, and ultra-smooth surface finish, these valves eliminate product hold-up and prevent bacterial growth.
Manufactured from AISI 316 / 316L stainless steel with FDA-compliant sealing materials, the valves are fully compatible with CIP (Clean-in-Place) and SIP (Steam-in-Place) processes. The integrated electric actuator enables accurate ON–OFF and modulating control, ensuring repeatable performance and seamless automation.
Designed for modern process plants, these valves integrate effortlessly with PLC / DCS systems, making them ideal for food, pharmaceutical, biotech, and high-purity applications.
