This thermostat device is provided with a housing, a thermo element that moves in an axial direction in accordance with the temperature of a coolant, a valve body that is caused by the movement of the thermo element to move toward and away from a valve seat provided to the inner side of the housing and open and close a communication section between a first flow-through port and a second flow-through port, and a biasing member that biases the valve body toward the valve seat. The housing is provided with a main body section, a first housing member having the first flow-through port and the second flow-through port, and a second housing member that has the third flow-through port and that is fastened to the first housing member by rotating in a circumferential direction in relation to the first housing member.

A precision ceramics control balance valve includes a valve housing, a rotary base mounted in the valve housing, a valve lever mounted on the rotary base and protruding upward from the valve housing, a movable valve plate mounted in the valve housing and located under the rotary base, a fixed valve plate mounted in the valve housing and located under the movable valve plate, a valve seat mounted on a lower end of the valve housing to stop the fixed valve plate, the movable valve plate and the rotary base, a temperature limiting device mounted in the valve seat, a pedestal connected with the valve seat, and a balance unit mounted in the pedestal.

The faucet of cartridge has an expandable temperature regulating rod in the main body. The temperature of water is regulated by changing the ratio of cold water and hot water by the movement of the temperature regulating rod. The water can be switched on or off by rotating the main body with respect to the seat. The main body includes an outer body, an inner body, and an anti-leaking element. The anti-leaking element is sandwiched between the outer body and the inner body to partition the space therebetween into two channels for cold and hot water to flow into the inner body.

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).

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 assembly for a faucet assembly includes a housing, a thermal motor and a sealing element. The housing includes a first inlet that receives water from a first source, a spout outlet in fluid connection with the first inlet, and a second inlet that receives water from a second source. The thermal motor is within the housing and imparts linear force in an axial direction. The sealing element is operably coupled to move in response to the imparted linear force, and is configured to engage a seating element to form a seal between the second inlet and the spout outlet. The seating element is disposed axially between the motor and the sealing element, and movement of the sealing element in the axial direction breaks the formed seal to allow fluid flow within the housing between the second inlet and the spout outlet.

Embodiments include thermostatic valves for showers and tubs in which the temperature is regulated by a thermostatic motor/element. Both the flow from the valve and the temperature are controlled by a rotary stem. Hot and cold water is pre-mixed by passage through the coils of a return spring into a mixing chamber and a ceramic valve at the top of the mixing chamber controls flow of mixed water from the mixing chamber into an outlet chamber where fluctuations in the water temperature are eliminated before the water is conveyed to the shower or tub.

A sanitary faucet having a faucet body; a mixing valve for mixing cold water and warm water to form a mixed water; and a thermostatic mixing valve for mixing cold and hot water to generate the warm water, containing an expansion material element and a gate valve operated by the expansion material element for adjusting a mixing ratio between the cold water and the hot water, wherein the expansion material element and the gate valve are arranged non-coaxially to each other, wherein the expansion material element can be used to operate the gate valve via a connection element, and wherein the connection element can be attached to the gate valve or the expansion material element and can subsequently be rotated into a closed position, in which the gate valve and the expansion material element are interconnected by the connection element. A method of installing a sanitary faucet is proposed.
