Abstract
A gate valve and method according to which a gate body extends within a valve cavity, a fluid bore extends through the gate body, and a passage extends from the fluid bore, through the gate body, and to the valve cavity. The valve cavity is pressurized with a lubricant to prevent, or at least resist, solid particles (e.g., sand, fines, debris, etc.) from entering the valve cavity. The valve cavity and the fluid bore are pressure balanced. In some embodiments, a flow valve, such as a check valve or one-way valve, is positioned within the passage.
