Hydraulic Shock Absorber max impact 252 mm - Designed for Sliding Fire Doors - 65000SV Opera

Use of Hydraulic Shock Absorber for Closing Safety Doors

Hydraulic shock absorbers are used as a limit switch to slow down the impact and therefore facilitate the closing of a sliding door thanks to the braking effect deriving from the passage of oil through holes and slots made in the cylindrical body.

By means of a regulation system, the degree of braking can be increased or decreased by opening or closing the oil passages through the piston.

The damper stem, once compressed, rearms automatically when the door is reopened by means of a special magnet, preparing itself for a new cycle.

Choice of safety valve

  • With safety valve
  • Without safety valve
  • (The safety valve is used to let the brake fluid out in case of fire and to avoid the spontaneous rearming of the piston rod due to the thermal expansion of the liquid)
