SSV PG6
Bolt Tensioner with immersion nut (puller)
Cost-reducing - Powerful - Reusable



Basic position
Place the SSV onto the bolt to be tensioned and screw the Thread Sleeve down to the Piston surface. A hydraulic high-pressure pump, through a flexible hose, feeds oil into the space between Cylinder and Piston. The hydraulic pressure increases.

Cylinder

Elongation and compression
As the hydraulic pressure increases, the resulting axial force elongates the Bolt and compresses the flanges. Thus, the Main nut lifts from the flange. On reaching the desired tension, pressurizing is stopped.

Main Nut

Positioning of the Main nut
The tensioning force is achieved and the Main nut can be turned down to contact the flange. When releasing the oil pressure, the desired tensioning force remains in the bolt connection. After removing the SSV, you may use the equipment for tensioning other bolts.
