Monel Check Valves are primarily crafted from Monel 400, a nickel-copper alloy that consists of about 63% nickel and 28–34% copper, along with trace amounts of iron, manganese, and other elements. This unique composition grants outstanding resistance to seawater, acids, and alkalis. On the mechanical side, Monel boasts a tensile strength of around 550–620 MPa and a yield strength of roughly 240–345 MPa. It retains its ductility and toughness even in sub-zero temperatures, making it perfect for challenging environments. The alloy’s remarkable mechanical properties ensure a long service life and minimal maintenance in critical fluid control systems.
