Abstract
Valve seats include a flexible arm portion configured to seal against a portion of a valve body of a valve. A ball valve may include such valve seats. Methods of forming a seal in a ball valve include forcing a first metal valve scat into sealing contact with a first end cap and a ball valve member with a first metal flexible arm member and forcing a second metal valve seat into sealing contact with a second end cap and the ball valve member with a second metal flexible arm member.
