Check Valves – ½” to 12”, Cast & Stainless Steel, Flanged/Threaded Ends

These industrial-grade check valves are designed to prevent backflow in fluid systems by allowing one-directional flow. Manufactured from a range of high-performance materials—such as cast iron, cast steel, forged steel, stainless steel (SS304/316), and bronze—these valves are suited for various applications including water supply, petrochemical processing, oil & gas, and steam lines. Available in sizes from ½” to 12”, these valves comply with ANSI, DIN, and JIS standards. They come in multiple pressure classes (PN10, PN16, CL150, CL200, CL900) and support operations up to 1000 PSI. End connections are offered as NPT threaded, socket weld, or flanged, making them adaptable for integration into both new and existing piping systems. Manufactured in the USA, Singapore, India, China, and Korea, these check valves deliver durability and leak-free performance for critical operations.
