How it works
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, TC valves provide casing protection from back flow through the injection valve. When gas flow is permitted into the tubing through the valve, the check dart is depressed. When the flow is from tubing to casing, the check valve seats. A metal-to-metal seal is established as differential pressure is increased.
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 valves. A primary application for these valves is preventing backflow from the injection valve, which may damage the casing. Other applications include preventing production commingling in dual gas-lift installations and improving pressure integrity during acidizing and circulation operations.
