The Hygienic 316L Welded Ball Valve is a permanent, high-integrity flow control solution for sanitary pipelines. By using Butt-Weld ends, it eliminates the leak paths and crevices associated with mechanical joints, ensuring maximum hygiene. Made from low-carbon 316L stainless steel, it features encapsulated PTFE seats to prevent product entrapment. It is 3A/FDA compliant, 100% CIP/SIP compatible, and ideal for high-purity steam or sterile fluid applications.
