<p>A shape memory effect actuated diaphragmatic antiscald valve, including a valve housing (10) having a fluid flow path therethrough and including a pilot chamber. There is a first valve seat (23) within the housing and a second valve seat (13) within the housing and downstream from the first valve seat. A pilot valve is located within the chamber of the valve housing for preventing fluid flow through the chamber in which the pilot valve element is located and a first valve element (42) is retained seated in the first valve by the pilot valve. There are means (36) including an SME element for controlling the open and closed positions of the pilot valve depending upon the temperature of the fluid flowing through the SME valve.</p> |
