Abstract
A gate valve seat seal includes a two-piece seat arranged so that an inner seat moves within an outer piece. The inner seat is moved by a flange where as the flange moves radially inwards the inner seat is moved axially to seal the gate. As the flange moves radially outwards the inner seat is moved axially out of sealing contact with the gate.
