Top Sanitary Check Valves Manufacturer in China
Sanitary Check Valves are specialized, non-return valves designed to maintain unidirectional flow in hygienic systems, preventing backflow and contamination. These valves operate automatically, using a disc, ball, or spring-loaded mechanism, ensuring reliable performance with minimal maintenance. Ideal for food and beverage, pharmaceutical, and biotech applications, sanitary check valves comply with standards like 3-A and FDA, offering corrosion resistance and compatibility with clean-in-place (CIP) and steam-in-place (SIP) processes.
