Abstract: A thermostatic valve incorporated within a plumbing system for regulating the flow of fluid. The thermostatic valve includes two valve assemblies operatively cooperating to preclude the flow of scalding water. The first valve assembly and second valve assembly respond to different fluid temperatures, as well as, over separate periods of time. The thermostatic valve can be incorporated in an “end-line” device such as a showerhead or faucet assemblies to create an “anti-scaled” plumbing fixture. The invention includes a valve housing having a first compartment and a second compartment, a fluid passageway, a first valve assembly, a second valve assembly, a first spring, a first stopper, a first flange, a first thermostatic cylinder, a second spring, a second stopper, a second flange, a second thermostatic cylinder, and a third spring.

Abstract: A quarter turn cast iron ball valve where the ball inside is cast of metal, solid or hollow, and forms a cylinder or tube across the inside. This tube is "open" on both ends so that when the ball is seated and turned to its open position there is a diametrically extended flow passage allowing the fluid to flow through the valve. The ball is covered with "Teflon" on the periphery of the ball as well as on the inside periphery of the tube. The gland plate has a locking mechanism which enables the valve to be quickly set to a desired position on a permanent basis and be locked in either the full, opened or closed position.
