The ASME B16.10 Check Valve is a flow control device designed to allow fluid flow in one direction only, as specified by the ASME B16.10 standard. It ensures installation interchangeability for valves of various materials, types, sizes, rating classes, and end connections. This valve, also known as a one-way valve, prevents backflow in systems, offering an affordable, effective, and straightforward solution to potential contamination issues caused by reverse fluid flow.
