Abstract
A thermostatic valve for mixing hot water and cold water includes a valve body defining a first inlet, a second inlet, a mixing chamber, a first passageway between the first inlet and the mixing chamber, and a second passageway between the second inlet and the mixing chamber. The thermostatic valve includes first and second flow control assemblies and first and second screen assemblies assembled into the valve body. A first screen assembly is positioned downstream of a first flow control assembly and a second screen assembly is positioned downstream of a second flow control assembly. Each screen assembly is removable from the valve body and includes a screen body having a screening portion with a lower open end and a top portion. The screen assembly includes a closing cap to retain accumulated particulate matter. A retaining clip is used to hold the screen assembly in position within the valve body.
