Abstract
A gate valve includes a body with a flow passage intersected by a gate cavity and a gate with an axis, the gate being axially movable in the gate cavity between a gate closed position and a gate open position. A lifting device is in engagement with a stem of the gate to move the gate to the gate open position. A port extends from a first external surface of the gate to a second external surface of the gate. A seal member is mechanically connected to the lifting device, the seal member being moveable in response to axial movement of the lifting device between a seal open position where fluids can flow through the port and a seal closed position where the seal member blocks fluids from flowing through the port.
