Abstract: The invention relates to a pilot valve arrangement (1) comprising a pilot valve device (2) which comprises a pilot valve element (13), a pilot valve seat (14) cooperating with the pilot valve element (13) and a presetting mechanism for presetting an opening pressure of the pilot valve element (13), the pilot valve arrangement (1) further comprising a presetting mechanism actuating device (3) which comprises an actuator element (17) adapted to create an actuating force in order to actuate the presetting mechanism in the pilot valve device so as to preset the opening pressure. According to the invention, the pilot valve arrangement (1) comprises a contactless force coupling arrangement adapted to transfer the actuating force from the presetting mechanism actuating device (3) to the pilot valve device (2). An inventive pilot valve device (2) is disclosed and claimed as well. The invention allows to improve maintenance and safety concerning the devices mentioned above.

Abstract: Servo valve with a main piston (5) and a servo piston (13). The servo piston controls a pressure in a servo chamber and thereby controls movement of the main piston based on a pressure difference between two chambers of the valve. To facilitate opening of the valve by relatively small pressures even in high pressure systems, the servo chamber (7) according to the invention is provided inside the armature (11).
