  • Lubrication system for valve seat of a gate valve
    Patent number: 5341835
    Abstract: A lubrication system for the block and bleed valve seat of a gate valve. Lubrication is provided to the seat through tubing which communicates with the exterior of the gate valve to supply the lubricant and the interior channels of the valve seat. Seals in the valve seat maintain the lubricant within the interior channels of the seat. The lubrication system allows the user to test each seat for integrity without exposing the entire valve to atmosphere by increasing lubricant pressure through the valve seat.
