The invention discloses a high-performance valve element. The high-performance valve element comprises a valve element body. An opening part is arranged at the upper end of the valve element body. An annular groove is formed in the exterior of the valve element body, a connection part is arranged on the periphery of the opening part, the joint of the opening part and the valve element body is a transitional segment, a first water passing opening is formed in the transitional segment, a second water passing opening is located below the first water passing opening, and a valve needle is arranged on the middle portion of the valve element body and located above the second water passing opening. The high-performance valve element has the beneficial effects that the structure is simple, the connection part is arranged on the periphery of the opening part, installation is facilitated, the diameter of the second water passing opening is larger than that of the first water passing opening, and accordingly the water flow noise generated by pressure at a water outlet of the valve element is effectively lowered; and the stability of the valve element can be improved through arrangement of the valve needle, and the service life is prolonged.
