Locking gas spring
Gastac Locking gas springs can be stopped in any stroke position, with a locking valve into the pressure tube, they only allow extension or compression when the release pin, located at the end of the rod, is depressed.
Locking Gas Springs from Gastac can offer optimum weight equalization during opening, closing and positioning. A special piston / valve system, which separates the two pressure chambers in the gas spring, allows effortless variable locking. If the valve tappet is released from the outside and the exchange between the pressure chambers is interrupted, the gas spring will lock and hold even heavy loads reliably in the desired position.
