The Flow Activated JDC Running/Pulling Tool is designed to run or retrieve downhole tools with conventional external fish necks. When the Flow Release JDC Running/Pulling Tool locates on the top of the fish, the tool can be engaged with the fish automatically by slightly pushing down the Flow Release JDC Running/Pulling Tool. The tool does not require shear pins or drop balls, and the pressure drop occurred will push the mandrel move down to release the fish while fluid passing through the tool.

• Flow activated release.
• Simple maintenance.
