Sanitary Decompression Valve

This sanitary pressure relief valve is constructed of premium AISI 304 or 316L stainless steel material with interior surface finish Ra0.8m, adopting a hygienic no dead zone structural design that prevents medium accumulation and contamination. Designed for overpressure protection of pipelines and storage tanks, it automatically opens to discharge excess pressure once the set pressure value is reached and reseals tightly when pressure returns to normal working range. Compatible with CIP clean in place and SIP sterilize in place processes, this valve is equipped with FDA approved food grade sealing elements and supplied with tri clamp, welded and threaded connection options. It is extensively used in biopharmaceutical, food & beverage, dairy, fine chemical, lithium battery and purified water systems to safeguard equipment and piping against damage caused by abnormal pressure surge.
