Abstract

A valve and associated components and methods, and a container including such a valve. The valve may be referred to as a non-rising stem gate valve. The valve includes a gate movable by a drive assembly to open and close the valve. The drive assembly includes a thrust bearing assembly configured to resist damage due to thrust force. The thrust bearing assembly can include a race threaded to a drive shaft of the drive assembly. The race can be pinned to the drive shaft by a roll pin.
