Abstract (en)
[origin: EP2025924A2] The device has a sealing surface (27) placed for sealing a fluid flow against a sealing surface (11) e.g. valve seat, of a valve element. One of the sealing surfaces is coated with a coating (21) made of a shape memory alloy. The sealing surfaces are designed as a flat seal. The sealing surface (27) is formed at a closing element (23) of the valve element. The closing element is formed spherical or conically. The shape memory alloy provides a reversible deformation after an effect of an external force. An independent claim is also included for a method for manufacturing a device for sealing a fluid flow.
