WD and WD-C SERIES DUMMY VALVES
The OPTI-FLOW WD and WD-C Series dummy valves are retrievable, isolation tools installed in a side pocket mandrel to block the mandrel’s injection ports. The valve with appropriate latch may be installed or retrieved prior to or after completion for various procedures.

WD Series Dummy Valves

  • The WD-1 model is a 1” O.D. valve
  • The WD-1.5 model is a 1-1/2” O.D. valve

WD-C Series Dummy Valves

Applications:
Used to seal off the pocket of a side pocket mandrel, preventing communication between the casing and tubing. These valves are also used to blank off the tubing for production until gas lift valves are required. Other applications include pressurizing the tubing in various procedures, isolating tubing and casing flow during single alternative production, and isolating tubing and casing flow for test purposes during multi point water or gas injection floods.

  • Two sets of packing to straddle and pack off casing ports
