Abstract
A temperature-actuated mixing valve for controlling outlet temperature in a fluid flow system including a valve housing having first and second inlets for introducing first and second respective supply fluids and an outlet. A shuttle assembly is positioned in the housing. A valve member is mounted within the housing and responds to the temperature of the supply fluids to vary their mixture ratio to dispense fluid at an outflow temperature. A shuttle member is positioned within the valve member, is moveable responsive to supply fluid temperature variation, and includes an elongate grip pad for manual removal of the shuttle member from the housing. A thermal actuator converts thermal energy into mechanical movement using a piston. A spring maintains the valve and shuttle members in a stationary condition relative to each other and permits movement of the shuttle member relative to the valve member for accommodating movement of the piston when the valve member has reached its limit of travel.
