The Pneumatic SS Sanitary 3-Piece Butterfly Valve is an automated, high-serviceability solution for permanent pipelines. The 3-piece design allows the central body to be removed from its welded end-flanges for maintenance without cutting the pipe. Controlled by a stainless pneumatic actuator, it supports remote automation in CIP systems. Made from SS316L, it is 3A/FDA compliant, offering a crevice-free, mirror-polished bore for critical food and pharma processes.
