This assembly comprises a casing, a thermostatic element and a slide. This slide is movable along an axis of the element so a first seat of the slide and a first seat of the casing delimit between them a first passage running around the axis and in which a hot fluid inlet opens and a second seat of the slide and a second seat of the casing delimit between them a second passage running around the axis and in which a cold fluid inlet opens. These first and second passages are closed when the slide occupies a first or second axial position, respectively, in which the first or second seat of the slide is in axial abutment against the first or second seat of the casing, respectively. They are open continuously all around the axis when the slide occupies an intermediate position between the first and second positions.

A single waterway valve core structure comprises a valve housing, a valve cover, a temperature regulating valve rod, a water stop piece, and a hollow water stop pad. A bottom of the valve housing comprises a water inlet cavity, and a side wall of the valve housing comprises a water outlet. The water stop piece is integrally formed on a bottom end of the temperature regulating valve rod, and the bottom end of the temperature regulating valve rod comprises one or more water passing holes. A side wall of the temperature regulating valve rod comprises a side outlet hole in communication with the water outlet. The hollow water stop pad is disposed in the water inlet cavity, the temperature regulating valve rod is disposed in the valve housing, and the water stop piece contacts the hollow water stop pad.

A hot water delivery system includes a water heater, a mixing valve that is coupled to the output of the water heater, and a plurality of loads that are coupled to the output of the mixing valve. A load set point temperature of each load that is representative of a maximum temperature of the hot water that is to be delivered to the respective load is set by a user. Responsive to detecting the occurrence of an event associated with a load of the plurality of loads, a controller of the water heater controls the mixing valve to adjust the temperature of the hot water from the water heater to the load set point temperature associated with the load, provided the load set point temperature of the load is different from a water heater set point temperature at which the water heater maintains the hot water therein.

A valve core connection structure of a valve assembly comprising: a body, two stop valve sets, two limitation structures, and two locking sleeves. The body includes a holder, a cold-water inflow connector, a hot-water inflow connector, a first outflow connector, a second outflow connector, a cold-water inflow seat, and a hot-water inflow seat. Each stop valve set includes a valve core, a limiting loop, a defining structure, and a locating structure. Each limitation structure is defined between a peripheral fence of each second accommodation cavity and the limiting loop so that the limiting loop is retained on the peripheral fence of each second accommodation cavity, thus limiting rotation of the limiting loop. Each locking sleeve is screwed on the cold-water inflow seat and the hot-water inflow seat so that the limiting loop and the valve core are limited in each second accommodation cavity.

A mixing valve (10) includes a valve body (12) having a hot fluid inlet (14), a cold fluid inlet (16), a mixed fluid outlet (18), and a cavity (20) in the valve body (12) between the inlets (14, 16) and the outlet (18). Mixing valve (10) includes a liner (30, 130, 230, 430, 530, 630, 730, 830) positioned in valve body (12) and a valve member (40, 140, 240, 340, 440, 540, 640, 740, 840) movable therein between a first position restricting the flow of hot fluid and a second position. Liner (30, 130, 230, 430, 530, 630, 730, 830) includes a downstream valve seat (74, 174, 274, 474, 574, 674, 774) that, when engaged by valve member (40, 140, 240, 340, 440, 540, 640, 740, 840), restricts flow of hot fluid past valve member (40, 140, 240, 340, 440, 540, 640, 740, 840).
