Abstract
A rotary gate valve includes first and second opposing housing members having coaxial pathways and defining a gate channel when joined together. A gate is positioned within the gate channel when the valve is in a closed position to prevent media from flowing through the pathways and rotationally displaced from the channel when the valve is in an open position to allow media to flow through the pathways. First and second annular primary sealing sleeves are disposed within the first and second housing members and are adapted to sealingly engage each other when the valve is in the open position, and with the gate valve when the valve is in the closed position. A secondary sealing member is disposed around an upper portion of the gate and secured between the housing members above the first and second annular primary sealing sleeves to prevent process media from entering the housing members.
