The ceramic valve core is usually composed of two ceramic pieces, one of which is a moving piece and the other is a static piece. The moving piece can rotate, and the opening and closing and flow of the water flow are controlled through the relative movement with the static piece. This structure design makes the ceramic valve core have very high sealing performance, which can effectively prevent water leakage.
