Patent number: 10094483Abstract: The disclosed embodiments include check valves capable of improved dynamic performance (e.g., closing and opening times). The check valves may include an annular disc having an opening. The annular disc may be lightweight and present a reduced surface area to the flow, thus increasing the closure speed of the check valve as well as the opening speed of the check valve. Other components, such as a spacer component, may be reconfigured to modify the check valve for increased performance in a variety of applications, including low flow volume, medium flow volume, and high flow volume applications.Type: GrantFiled: May 27, 2015Date of Patent: October 9, 2018Assignee: Cameron International CorporationInventors: Christophe Avdjian, Michael G. Dempster
