Abstract: A method for simultaneously unblocking multiple blocked valve fittings is described. The method includes coupling a tool to unblock multiple valve fittings simultaneously to a valve with multiple valve fitting blocked to fluid flow. The tool includes a pressure vessel holding a cleaning fluid, an input conduit fluidically coupled to the pressure vessel to flow the cleaning fluid from a cleaning fluid source to the pressure vessel and to adjust a pressure of the pressure vessel, and injection conduits to flow the cleaning fluid from the pressure vessel to the valve fittings. The method includes simultaneously flowing the cleaning fluid from the pressure vessel through the injection conduits to the valve fittings. Responsive to flowing the cleaning fluid to the valve fitting, the valve fittings are unblocked.

Abstract: A gate valve system includes a gate valve that has a housing with a first tubular body and a second tubular body separate from the first tubular body. The gate valve has a gate that moves to interrupt or allow fluid flow from the first tubular body to the second tubular body. The system includes a first seat disposed at a first annular reassess and defines an interior channel configured to receive pressurized fluid from a fluid injector. A second seat disposed at a second annular recess defines a second gap with the second annular recess. The second gap receives the pressurized fluid from the interior channel of the first seat to expand the second gap to move toward the surface of the gate to form an emergency seal with the gate as the pressurized fluid expands the second gap.
