Abstract

A position measuring system, especially for hydraulic valve, having a pressure tube to accommodate an armature is provided, whereby the pressure tube is manufactured by deep-drawing. As a result, a cost-effective manufacturing process can be employed for the pressure tube. The pressure tube can be firmly attached to a valve housing by means of a holding element and, optionally, an attachment flange.
