Brief Introduction

Sanitary Pneumatic Butterfly Valves are advanced flow control devices specifically engineered for hygienic processing applications. These valves combine the efficiency of quarter-turn operation with automated pneumatic control, making them ideal for industries requiring strict cleanliness standards such as pharmaceuticals, food and beverage, and biotechnology.

The valve features a precision-machined disc and seat assembly enclosed within a 316L stainless steel body with electropolished finishes (Ra ≤ 0.38 µm). The pneumatic actuator provides reliable automated operation while the sanitary clamp ends (Tri-Clamp, DIN, or ISO standards) ensure easy installation and maintenance. Designed with zero dead leg construction, these valves support full CIP/SIP processes and maintain the highest sanitary standards throughout their operation.
