The first seal ring cooperates with the valve member to close and seal the flow channel. The second seal ring cooperates with the valve member to seal the actuator bore. The seal rings are composed of radially extending metal lamellae interposed between soft material lamellae. The soft material lamellae are composed of lubricating material having a non-homogeneous structure which have the capacity to form radial freely extending sliding layers. The metal lamellae have, at least in the region around the inside surface of the seal rings, axial deformations. Such axial deformations provide positive mechanical connection to the adjoining soft material lamellae, restricting the soft material sliding layers to at most one third of the lamellae thickness.
