• F15B 9/09 with electrical control means
• F15B 9/1 in which the controlling element and the servomotor each controls a separate member, these members influencing different fluid passages or the same passage
• F15B 9/12 in which both the controlling element and the servomotor control the same member influencing a fluid passage and are connected to that member by means of a differential gearing
