Toyo and Red & White Bronze Check Valves (Swing)


A check valve is used to prevent backflow. Some check valves only work when installed in a horizontal manner. Check valves do not have operating mechanisms because the valve operates automatically, depending on the pressure of the flow. In sensitive systems, "cracking pressure" is the back pressure at which the check valve becomes engaged. New as of January 2014, brass fittings, pipe, and valves containing lead in excess of 0.25% will no longer be permitted for use in potable (drinking and cooking) water systems in Canada or the USA. This law applies only to products used to transfer water in systems which are directly for human consumption; it does NOT apply to any other application.
