Self-Lapping Valve FeaturesRotation of the disc produces an action that, in the process medium, renews and polishes the metal searing surfaces with each operation. This unique concept causes the Everlasting Valve to wear in with use, while all other valves are busy wearing out.
The self-lapping disc rotates as the center of the applied force and the centroid of friction force move toward alignment. High cycling is beneficial. Scratches that develop on the wide sealing surfaces are polished away as the valve is open and closed. There's no other valve like it.
