Brief Introduction

Sanitary Threaded Butterfly Valves are precision-engineered flow control devices specifically designed for hygienic processing applications in food, beverage, pharmaceutical, and biotech industries. These valves feature a threaded connection system that ensures secure, leak-proof installation while maintaining the highest sanitary standards. The compact disc-style closure mechanism rotates 90 degrees to provide quick and reliable flow control within sanitary piping systems.

Manufactured from 304 or 316L stainless steel with mirror-polished finishes (Ra ≤ 0.8 µm), these valves incorporate FDA-compliant EPDM, Silicone, or FKM seals. The threaded connections typically conform to SMS, DIN, ISO, or NPT standards, enabling seamless integration with existing sanitary piping systems while facilitating easy installation and maintenance.
