Improved Gate Valve for Mitigating Grease Loss in a Well Fracturing Environment, and Method of Use Thereof

A method of use for a fracturing gate valve comprising the steps of controlling flow within a pipeline using a gate valve, said gate valve comprising

• a valve body defining a flow passage and a gate cavity;
• a gate assembly positioned within said gate cavity, said gate assembly comprising
• a gate comprising a gate hole movable between
• a closed position wherein said gate is positioned such that a solid surface of said gate aligns with said valve seats blocking the flow through said passage;
• and
• an open position wherein said gate is positioned such that said gate hole aligns said passage enabling fluid flow through said passage;
• a valve seat positioned adjacent to said flow passage to form a sealing engagement with said gate assembly in said closed position;
• a support plate positioned above said valve seat within said gate cavity, said support plate configured to retain lubrication within said valve body and maintain consistent contact between said valve seat and said gate assembly during operation;
• and
• a plurality of grease fittings integrated into said valve body to supply lubrication to said gate assembly, said valve seats, and said support plates within said gate cavity.
