Abstract
A ceramic control valve of a faucet including a water stopping seat which is provided in the periphery thereof with a retaining edge. The water stopping seat is disposed in a floating fashion in the cylindrical valve body of the ceramic control valve such that the retaining edge of the water stopping seat is retained in an annular recess of the cylindrical valve body. The service life spans of the washers of the stationary valve block of the ceramic control valve and the circular surface of the faucet are thus prolonged.
