INJECTION PRESSURE OPERATED GAS LIFT VALVES

TP SERIES GAS LIFT VALVES
The OPTI-FLOW TP Series gas lift valves are tubing retrievable, injection pressure operated valves with a nitrogen charged dome and bellows configuration. The valve’s dome charge pressure is calculated for proper valve operation at the designed depth and temperature of operation. The dome pressure charge is preset prior to installation in the gas lift mandrel. These normally closed valves are opened after the gas lift injection pressure overcomes the downward force of the dome charge pressure above the bellows.

TP Valve Series
  • The TP-1 model in this series is a 1 O.D. valve.
  • The TP-1.5 model is a 1-1/2 O.D. valve.
Applications:
Used for intermittent or continuous flow applications with tubing retrievable gas lift mandrels. Smaller size valves are available for use with the IM and CT-IM special application mandrels for packoff, special clearance and smaller diameter installations.
Features:
  • Large dome volume improves operating efficiency of valve
  • Optional reverse flow check valve (TP-1 and TP-1.5 models)
  • Mechanical travel stop increases the cycle life of the bellows
  • Three-ply Monel® bellows
  • Silicon fluid bellows protection
  • Replaceable floating Monel® seat (tungsten seat available)
  • Silver-brazed bellows connections
  • Stainless steel or Monel® materials available
  • Pressure rating up to 1800 psi Ptro maximum
  • Temperature rating of 250º F (standard service)
  • Port sizes from 1/8” to 1/2"
