  • Completions
  • Safety backup valve


  • Unlimited number of cycles
  • Reliable closing force
  • Low operating pressures with high differential across the ball
  • Low nitrogen pressure on surface
  • Lock open position to safely run wire line or coil tubing
  • Fail closed position to provide an automatic emergency down hole close
  • Suitable for all conditions: high hydrostatic, H2S, acid, and heavy drilling fluids

The M2 Tester Valve is an annular pressure controlled, unlimited cycle, down hole Test Valve designed for use in HPHT environments. The tool features a lock open mechanism to safely run through tubing services including coiled tubing, wire line, and slick line. The M2 Tester Valve can operate under extreme differential pressures, with minimal increase in operating pressure due to the internal bypass which equalizes pressure across the ball valve prior to cycling the tool to the open position. The M2 Tester Valve can be combined with the Boost Hydraulic Delay tool to allow a customized and precise desired operating pressure.
