Abstract

A changeover valve (3) for gas or fluid with servo drive, has a T-shaped three way body for alternating through-flow of a fluid. In the inner chamber (9) of this body a closure unit (4) adjustable between two of the three ways is arranged. This unit comprises a cylinder adjustable in tow directions, controllable by means of an outside control source. The servo drive is installed in the closure in an axial direction with face sided sealing. The thrust cross section of the servo drive inserted in the movable closure unit is smaller than the sealing cross section of the flow to the two lateral connections. The adjustable closure unit with servo drive comprises a cylinder adjustable along a rigid bar to which is fitted a piston (10) located in the cylinder.
