<p>A three-way valve is installed within the axial control valve closing the access of a medium to the measurement and storage chamber. Consequently, a measuring and filling pipe can be adjusted during operation and under the operation pressure. Besides, an additional sealing lip is installed on a sealing insert of the axial valve disk, enabling a more reliable sealing of the disk to be achieved as by a mere screw head.</p> |
