ABSTRACT:
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. This avoids the disadvantages of variable positionable discs, while retaining their advantages. 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.
