Abstract

A valve is equipped with a closing element capable of being adjusted by means of a valve shaft and equipped with a flow divider. The latter is equipped with an actuating drive by means of which the flow divider can be adjusted as a function of the degree of aperture or opening of the closing element of the valve. The flow divider may be installed downstream of the valve and is made in form of a sliding bolt valve with a flangeless housing. The valve shaft of the valve is equipped with a displacement transducer which detects its position and is connected via a control device to the actuating drive of the flow divider.
