OPTI-FLOW offers a wide range of latches for installing wireline retrievable gas lift and chemical injection equipment in side pocket mandrels. Latches are specifically designed to lock in place when located in either a 180º or a 360º latch pocket profile. To retrieve a latch and attached valve, upward jarring of the tool string shears the release shear pin, permitting the locking mechanism to disengage from the latch pocket profile
