Abstract
An anti-scald water valve assembly comprises a body including a passage for water, a valve provided in the passage for shutting off the passage, and an electro-mechanical actuator to cause closing of the valve. A temperature sensor senses the temperature of water running through the passage. An electronic operating circuit is connected to the actuator and the sensor for activating the actuator to shut off the passage in response to the sensor sensing the water temperature exceeding a predetermined limit.
