Abstract
A device for opening or closing a seal seat of a valve arranged in a pipe for liquid or gaseous media includes a one-time only activation of the valve using a shape memory actuator. The shape memory actuator changes its external shape abruptly when a transformation temperature is reached that is dependent upon its alloy composition. The transformation temperature can be generated by a controllable electrical heating device of the device.
