Description
Retrievable Drop-in Check Valve

The Retrievable Drop-in Check Valve is an inside blowout control valve designed for drilling operations. It features a landing sub that connects to the required position in the drill string and is placed into the well to position the check valve assembly.

Key Features & Benefits
  • Prevents backflow during well kick situations
  • Allows downward liquid injection into the circulation well for conventional drilling operations
  • Controls pressure during drilling and significantly improves well control simplification
  • Automatically positions on the landing sub when dropped in, achieving blowout prevention
  • Easier disassembly compared to previous drop-in check valves, saving manpower and resources
