Drop-In Check Valves

Crossover's Drop-in Check Valve is a retrievable check valve. It is retrievable by means of a retrievable tool (gravel girdie) run in on wireline. When needed the check valve is pumped down the drill string to the landing sub. The dogs are locked in place with pressure from below the valve. The check valve will open to allow circulation and close when circulation is stopped.
