Check valves control the flow direction of fluids and are available in various configurations. Single-configuration check valves are designed to prevent back flow in only one direction. Double-configuration check valves control flow bi-directionally by diverting fluid to multiple outlets consecutively. Single-configuration check valves are normally closed, requiring positive pressure differential to allow flow, and are available with various termination options including luers, bond sockets, bond posts, and barbed designs. There are several opening pressure ratings from precision near zero to the anti-siphon valves which have higher opening pressures to prevent gravity induced flow. Medical-grade check valves are made with USP Class VI materials deemed safe for use with the human body. Medical-grade check valves reduce the risk of contamination, allow seamless priming, and offer higher flow rates. They are ideal for medical device designers focused on infusion, drainage and irrigation applications.
