GAS LIFT CHECK VALVES

TC SERIES CHECK VALVES
The OPTI-FLOW TC Series valves are tubing retrievable, spring loaded check valves with an NPT bottom connection. Used in conjunction with tubing retrievable injection valves that do not have an integral check valve, these valves provide casing protection from back flow through the injection valve. When the gas flow is permitted into the tubing through the valve, the check dart is depressed. When flow is from tubing to casing, the check valve seats. A metal-to-metal seal is established as differential pressure is increased.

TP Valve Series
  • The TC-1 model in this series is a 1” O.D. valve.
  • The TC-1.5 model is a 1 -1/2” O.D. valve.

Applications:
These valves are used with tubing retrievable gas lift valves that do not have an integral check valve, such as the TP-1 and TP-1 .5 gas lilt valves. A primary application for these valves is preventing back flow from the injection valve which damages casing. Other applications include preventing production commingling in dual gas lift installations and improving pressure integrity during acidizing and circulation operations.

Features:
  • Stainless steel or Monel® materials available
    Inconel® spring
  • Eliminates need to re-unload annulus liquid since valve prevents annulus fill up during shut down periods
  • Combination resilient metal-to-metal seat for bubble tight seal
  • Seal system options available
  • Valves can be stacked for additional protection
