Fluid Viscous Damper (FVD - Valve Type)

Fluid Viscous Damper which resists motion via viscous friction, the resulting force is proportional to the velocity but acting opposite direction, slowing the motion and absorbing the energy.

ACTS-SDT offers Fluid Viscous Damper (FVD), leads by international seismic expert Prof. Tony Yang, will simply and efficiently raise structural damping 20%~25% versus 1%~3% for a typical un-damped design. Our goal is to meet all technical performance applications outlined by the Structural Specification and provide a damper design with long service life.
