Abstract
Method and apparatus for the control of fluid flow using a flexible disc that is positioned in a control channel and restricted to movement along the longitudinal axis of the channel. Closure control is exercised by moving the disc into closer contact with a ring seat that is essentially self-purging of debris. Since the disc is confined to essentially longitudinal movement, distortion due to random lateral movement is avoided.
