AISI 316 disc check valves provide reliable, high-performance backflow protection for industrial and process applications. Made entirely of AISI 316 stainless steel with metal-to-metal sealing, they ensure durability, corrosion resistance, and long service life. With nominal pressures PN6/40 and sizes from DN15 to DN100, these valves guarantee secure unidirectional flow and consistent performance for water, air, and process fluids.
