Abstract
In one instance, a dynamic slab gate valve includes a valve body having a through-bore formed therethrough; a round gate cavity formed within the valve body and orthogonal to and bisecting the though-bore; and at least two retrofit slabs located within the round gate cavity. The retrofit slabs form a slab gate cavity having two parallel planar sides. A slab gate is disposed within the slab gate cavity. In another instance, a method for retrofitting a round gate valve includes the steps of removing a round gate from a round gate cavity of the round gate valve; installing a plurality of retrofit slabs within the round gate cavity to form a slab gate cavity; and installing a slab gate within the slab gate cavity. Other instances include seat assemblies and dynamic skirt assemblies.
