Gedore Torque DVV/DVI series of torque multipliers enables existing torque wrenches to deliver a much wider range of torque output, accurately and consistently. With a DVV/DVI torque multiplier, a single torque tool can be used for a greater number of applications. For the user, this means greater flexibility, fewer tools to carry around, and enhanced capabilities from smaller and lighter tools. For your company, this means increased efficiency and reduced inventory costs.

  • For use with a torque wrench
  • Mechanical hand torque multiplier for controlled screw tightening and loosening screw connections
  • DVV-540RS model equipped with fixture for welding on a reaction arm
  • RS models have anti-wind-up ratchet
  • Planet gear
  • High performance aluminum housing
  • Output square with drill hole for impact sockets with safety pin and ring
  • DVV models: Z-form offset reaction arm depending on model made of chrome-vanadium steel
  • DVV models only: Non-destructive “slipper” overload safety mechanism for gear protection – clockwise and counter-clockwise; Can be optionally retrofitted with L-form straight reaction arm with adjustable reaction arm of lightweight metal
