A water valve cartridge includes an operation disk which is provided in an assembly space between a cartridge base and a cartridge housing and adjusts degrees of opening and closing of an introduction passage and a discharge passage according to a rotational state so as to adjust an amount of water flow and a water temperature, wherein a cold water introduction hole and a hot water introduction hole which are introduction passages of water supplied from an external source and a plurality of discharge holes which are discharge passages of the introduced water have different rotation radii and are located on the same plane and the operation disk individually opens and closes the cold and hot water introduction holes and the plurality of discharge holes by a separate rotational operation in a state of being stacked in a surface-to-surface manner at a position corresponding to the different rotation radius.

A thermal management valve module is provided which includes a housing with at least one flow chamber. First and second valve bodies are rotatably positioned in the housing, and control the opening and closing of ports located on the housing. The first and second valve bodies include fluid pathways that allow flow through the first port and second port, dependent upon rotational positions of the valve bodies. First and second actuator shafts extend in the housing, the second actuator shaft is hollow and the first actuator shaft extends, preferably concentrically, through the second actuator shaft. The first valve body is rotationally fixed to the first actuator shaft and the second valve body is rotationally fixed to the second actuator shaft allowing separate positioning of the first and second valve bodies.

A fixed valve plate having a fixed valve central water passage and a fixed valve side water passage; a first movable valve plate having a first movable valve central water passage; and a second movable valve plate having a second movable valve central water passage and a second movable valve side water passage; wherein two end surfaces of the second movable valve plate are respectively sealedly attached to corresponding end surfaces of the first movable valve plate and the fixed valve plate; and wherein rotating of the first movable valve plate causes the first movable valve central water passage and the second movable valve central water passage communicated or noncommunicating, and rotating of the second movable valve plate causes the second movable valve side water passage and the fixed valve side water passage communicated or noncommunicating.

A spray gun includes a spray gun main body and an adjustment valve. The spray gun main body has an air intake passage, a first air outlet passage, a second air outlet passage, and a mounting hole defined therein. The mounting hole is in communication with the air intake passage, the first air outlet passage and the second air outlet passage. The adjustment valve is mounted to the spray gun main body and located in the mounting hole. The adjustment valve includes a first operating member and a second operating member. The second operating member is movably mounted on the first operating member.
