A plumbing component for controlling the mixture of two supplies of water having different temperatures, the plumbing component comprising:

• a cold water inlet configured to receive a supply of cold water;
• a hot water inlet configured to receive a supply of hot water;
• an outlet configured to output cold water or hot water or a mixture thereof;
• a flow shut-off mechanism operable to restrict the flow of water out of the outlet;
• a first flow control valve for controlling the flow of cold water from the cold water inlet to the outlet;
• and
• a second flow control valve for controlling the flow of hot water from the hot water inlet to the outlet;
• wherein each of the flow control valves comprises a valve member and an associated valve seat, each valve member arranged to engage with the associated valve seat to control the flow of water through the flow control valves to the water outlet;
• and
• wherein one or both of the valve members comprises a graduated flow control bead arranged to seal against the associated valve seat to provide a graduated flow transition between a maximum flow state and a minimum flow state of the, or each, control valve.
