Mixing valve

A valve for use in a plumbing fixture for washing, bathing and showering, the valve being configured to control the mixing of a supply of cold water and a supply of hot water, the valve comprising:

• a housing comprising a first inlet chamber defined by a first chamber wall and configured to receive the cold water, a second inlet chamber defined by a second chamber wall and configured to receive the hot water, and a mixing chamber configured to receive the cold water from the first inlet chamber and the hot water from the second inlet chamber, wherein at least a portion of the mixing chamber is located between the first chamber wall and the second chamber wall;
• a first flow control valve extending through the first inlet chamber and moveable relative to the housing for controlling the flow of cold water from the first inlet chamber to the mixing chamber;
• and
• a second flow control valve extending through the second inlet chamber and moveable relative to the housing for controlling the flow of hot water from the second inlet chamber to the mixing chamber.

• a first flow control valve moveable relative to the housing for controlling the flow of cold water from the first inlet chamber to the mixing chamber;
• a second flow control valve moveable relative to the housing for controlling the flow of hot water from the second inlet chamber to the mixing chamber;
• and
• a heating element located in the housing and provided adjacent to the mixing chamber to heat the housing to a temperature to disinfect an internal waterway of the housing.

A valve for use in a plumbing fixture for hand washing, bath filling and showering, the valve being configured to control the mixing of a supply of cold water and a supply of hot water, the valve comprising:

• a housing comprising a first inlet chamber configured to receive the cold water, a second inlet chamber configured to receive the hot water, and a mixing chamber configured to receive the cold water through two flow control openings from the first inlet chamber and the hot water through two flow control openings from the second inlet chamber;
• a first flow control valve for controlling the flow of cold water to the mixing chamber through the two flow control openings from the first inlet chamber;
• a second flow control valve for controlling the flow of hot water to the mixing chamber through the two flow control openings from the second inlet chamber;
• wherein each flow control opening has a size and the mixing valve has a flow coefficient that when both the first and second flow control valves are in a full open position, the valve outputs a first flow rate of water;
• when both the first and second flow control valves are in a mid-open position, the valve outputs a second flow rate of water;
• and when both the first and second flow control valves are in a position that is less than the mid-open position, the valve outputs a third flow rate of water.
