Abstract
A sealing arrangement for an actuator, in particular a valve stem, that is movably mounted in a housing, includes a single-piece, profiled seal body which encircles the actuator in form of a sleeve. The seal body bears upon the actuator under bias and has several ring-type gaskets in form of axially spaced O-ring sealing sections and annular lip sealing sections at the axial ends of the seal body, for sealing fluid and working spaces.
