A closing system for controlling a flow with precision Abstract The closing system comprises a closing member, a carriage to translationally displace the closing member along rails which counter- weight the force exerted against the closing member. A type of jack is mounted on the carriage for non-resilient axial displacements of the closing member to and from a flow opening. A damper having numerous functions, transmits the vibrations of the closing member to the carriage and ensure axial displacement of the closing member. The closing member being submitted to the damper, closes the flow opening by first axially aligning the closing member with respect to the flow opening by actuation of carriage. The jack axially displaces the closing member to urge the closing member against the flow opening, to close it without translational displacement and away a minimal dis- tance therefrom for clearance and then the carriage is actuated to reduce or enlarge the flow opening, with precision and without fric- tion from translational displacement on the flow opening. A method to damp while opening or closing a flow opening is also disclosed.
