Abstract
A gate for a gate valve includes a first body portion and a second body portion. The first body portion has a disc shape and a first wedging element extending from the disc shape. The second body portion has a disc shape and a second wedging element extending from the disc shape. The second body portion is pivotably connected to the first body portion. A gate valve includes a valve body and the gate. The valve body includes a first opening, a second opening, a flow passage from the first opening to the second opening, and a gate channel intersecting the flow passage. The gate is configured to move along a center axis of the gate channel between a closed position where the gate is fully in the flow passage to block fluid flow through the flow passage and an open position where fluid can flow through the flow passage.
