Gas Springs with a lockable piston rod and delayed return stroke
CONTROLLABLE GAS SPRINGS
Eliminating the need for a hydraulic cushion or double action press , FIBRO Controllable gas springs (KF springs) are gas springs which can be locked in their bottom position. The timing of the return stroke can be controlled to suit the application.

For best results the stroke length must always be used to the full with a tolerance of ± 0.5 mm. For this reason the springs are available with any stroke length from 4 to 167 mm in 1 mm increments.
The gas spring return stroke can be controlled electrically or pneumatically from either the tool or the press end. In the basic version of the gas spring (KF), it returns about 1 mm before it is held in the bottom position. This spring back effect can be eliminated, if required, by connecting the KF gas spring to a passive gas spring (KP) via a valve block. This is known as a KF + KP system.
