More Information
Summary:A damping system for a valve with a flapper comprises a main body having at least an inner wall defining a chamber having fluid therein, a paddle disposed within the chamber, and a fluid channel. The paddle is coupled to the flapper and moved thereby between a first and second position when the flapper is in a closed and an open position, respectively, and is configured to force fluid from at least a section of the chamber when approaching the first or second position. The fluid channel is coupled to the chamber section, and is configured to allow fluid egress out of the chamber section at a first egress rate when the paddle moves from the first position to a predetermined intermediate position between the first and second positions, and at a second, lower egress rate when the paddle moves from the predetermined intermediate position to the second position.
