Piston sliding door damper ZDH series

Bi-directional dampers for sliding lift doors The DICTATOR sliding door dampers of the ZDH series are bi-directional hydraulic dampers for an impact speed up to 2.0 m/sec. A single damper will slow down and damp the door in the final stages. For this purpose the damper is fixed to the door and corresponding limit stops have to be provided in the respective open and closed position. All DICTATOR dampers of the ZDH series are adjustable. This allows the door to be adjusted to an optimum function. Depending on the requirements we offer different ZDH types: with automatically extending piston rods, with the piston rods pushing/extending one another or with one piston rod extending automatically and one being pushed by the other.
