EQUALIZING DUMMY VALVES

WED SERIES EQUALIZING DUMMY VALVES
The OPTI-FLOW WED Series equalizing valves with integral latches are virtual dummy valves designed to provide controlled equalization or circulation between the casing and tubing. The downward shifting of the latch opens the communication port, allowing circulation or equalization. Once shifted, the valve can be pulled in the same trip as the integral top latch and redressed, if needed.

WED Valve Series
  • The WED-1 model is a 1” O.D. valve
  • The WED-1.5 model is a 1-1/2” O.D. valve
Applications:
Primarily used to equalize casing and tubing pressure, the most common application is multiple water flood zones isolated by packers. After equalization, the valve must be pulled and redressed, if needed, to prevent communication between the casing and tubing. The valve may also be 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.
Features:
  • Stainless steel or Monel® materials available
  • Two sets of packing to straddle and packoff casing ports
  • Integral top latch to equalize tubing and casing pressure
  • Fluid circulation after equalization
  • Equalizing feature for controlled flow during equalization prior to removing
  • Equalizing and pulling operation can be performed in one trip
  • Standard Nitrile® packing element system with other packing materials available
