Abstract
A mixing valve according to the invention allows fluids such as hot and cold water to flow through a pair of inlet ports, mix together and then exit through an outlet port. A check valve in each inlet allows the incoming fluid to flow in a forward direction, but prevents any reverse or crossover flow. An adjustable stop, positioned intermediate the valves, regulates the extent to which each valve can open to provide a desired mixing ratio of fluids, and can also be used to close one of the check valves. An actuator connected to the adjustable stop permits manual control of the mixing ratio.
