Abstract: A flow control device includes a valve body, a first port disposed on the valve body, a second port disposed on the valve body, a gate disposed within the valve body and configured to control a flow of a fluid between the first port and the second port, and a seat disposed between the gate and the valve body, the seat including a first surface configured to form a circumferential seal with the valve body and a second surface configured to form a face seal with the gate. A method includes receiving, by a sealing assembly forming a circumferential seal between a seat and a valve body, a first force from a collar disposed on the seat in response to a first movement of a gate, and moving, in response to receiving the first force, the sealing assembly in a first direction of the first force.
