The DBT-Series Hydraulic Bolt Tensioners will ensure uniformed gasket compression. Compression is essential for the integrity of critical bolted flange connections. Unlike a torque wrench, the DBT-Series Bolt Tensioners are capable of tightening more than one bolt at a time and can apply a consistent torque via direct axial stretching to any given number of bolts simultaneously. These tensioners have been designed to fit all standard ANSI & API flanges with quick release bridge and hexagon socket for fast change over. There are 10 load cells from M20 to M150 or 3/4" to 5-3/4" and they are light and easily handled.
