Isolation Fluid Viscous Damper 

ACTS-SDT offers Fluid Viscous Damper (Isolation FVD) is a high-performance damping device specifically designed for isolation layers. It utilizes high-viscosity fluid and a piston mechanism, featuring long-stroke and linear damping characteristics. The device effectively absorbs energy and controls structural displacement during earthquakes or sudden external forces, reducing acceleration in the superstructure. At the same time, it allows slow movements of the isolation layer under normal conditions, maintaining structural comfort and durability.
