A sanitary check valve is a specialized valve designed to prevent the backflow of fluids in sanitary systems. It is an integral part of hygienic processing systems and is widely used in industries such as food, beverage, pharmaceutical and biotechnology.
The main function of the sanitary check valve is to ensure one-way flow of fluid, thereby preventing system contamination. It works based on an internal spring spool design that allows fluid to flow forward through the valve while preventing backflow.
Sanitary check valves are typically made from high-grade, non-corrosive materials such as stainless steel and are designed to be easily removed and cleaned. The internal seal is made of EPDM or PTFE, which fully complies with hygienic conditions.
