Technical Data The FVD-B Series dampers are typically utilized on bridge and base isolation platforms requiring a long cycle life. This custom orifice designed damper provides the desired force versus velocity relationship symmetrically in both tension and compression directions, thermal compensation, and easy preventative maintenance inspection. Note: 1. Various stroke lengths available. Pin-Pin length at mid-stroke position can be determined by adding 2.5x the stroke length change. 2. Velocity exponent a is available from 0.2 - 1.0 3. Weight and dimensions are for reference only. Consult ITT...
