Hygienic check valve 3A, 316L Stainless Steel
SY-CKV
Hygienic check valves are also named as hygienic non-return valves. They are spring check valves, managing the flow of process liquids and gases through hygienic process systems to prevent reverse flow. Hygienic check valves are alomost used in all types of systems through heat exchanger, AI liquid cooling systems, food-processing, beverages, brewing, wine, dairy, cosmetic, personal care, pharmaceutical, biotechnology and semiconductor industries.
