Torque Tool
Torque Tool
The TMT AM1 Gripper Tool was originally designed to remove the valve insert from the needle valves on subsea trees. In order to apply a higher torque than the insert will allow, or to use the AM1 Valve Hole Cutting Tool, the insert needs to be removed using the Gripper tool.
The Gripper Tool consists of a threaded actuator, attached to the ROV handle, which is driven underneath a wedge that expands to grip the valve insert. As the actuator and the wedge are linked together, when the handle is wound out, the grip will release, allowing the valve insert to be reinstalled if required.
TMT can customise the tool to suit your requirements.
