Abstract
A thermal control valve provides more accurate control of the valve outlet temperature for a high flow rate valve in a low flow rate environment. The valve utilizes a thermal motor to close the valve during high temperature operation and includes flow-directing element that restricts the flow of water through the valve at low pressures and directs the flow of water toward the thermal motor. The flow-directing encircles the thermal motor and is formed from a flexible material so that it expands under pressure of water flowing through the valve.
