Abstract
Temperature control valve apparatus for preventing back flow from a cold water line into a hot water line includes a housing having an inlet or connection to a hot water line, an outlet for a connection to a cold water line and an interconnecting bore with a valve seat. A removable valve plug is disposed in the bore proximate the valve seat and a valve spring biases the valve plug in a spaced apart relationship with the valve seat for enabling water to flow therepast and through the housing from the hot water line to the cold water line. A thermal actuator disposed in an operative position for moving the valve plug to a seating position against the valve plug is provided to prevent water flow therepast from the cold water line to the hot water line.
