how it works
The handle is rotated by the WROV manipulator, the nut fixed to the stopper bolt transfer it to its end positions. The flexible handle is equipped with links to prevent bending of the drive screw.
The indicator shows the correct positions for the stopper bolt. In the end positions the pig stopper has metal seals to give a leak tight permanent connection for the internal pressure.
