The hydraulically activated tool is designed to move the sleeve to in open and close positions.
The tool is designed to guarantee reliable engagement and movement of the sleeve under a great force created by the fluid pressure inside sealed working cavities.
When running the tool in the hole in the transport position, it cannot be unintentionally activated and engaged as the maximum external diameter enables the slip dies to be locked deep inside.
Activation pressure can be optionally adjusted according to customer requirements.
