Abstract
An electromagnetically actuatable proportional valve (10) includes a valve part (14) with an actuator that controls pressure fluid connections, an actuator solenoid (12), and with a set of control electronics (16), controls the activation of the coil. The control electronics (16) are flanged mounted onto the actuator solenoid (12) or the valve part (14) and is thereby exposed to mechanical and/or hydro-mechanical vibrations. In order to vibrationally decouple the control electronics (16) from the valve part (14) and/or the actuator solenoid (12) at least one vibration-damping means in the form of a damping plate (18) between these components and the control electronics (16) is provided.
