Abstract (en)
[origin: WO2022112317A2] The invention relates to devices (100) for actuating a control element (110), which devices can be safely and reliably operated in an environment at risk of explosion or fire. For this purpose, a device (100) is proposed in which the control element (110) is actuated by means of a magnetic field of an electromagnet (130), which is located in a flameproof housing (120). The magnetic field of the electromagnet (130) is conducted out of the housing (120) by means of a flux-conducting piece, which extends through the housing (120) in such a way that flameproofing is ensured. In this way, the magnetic force which the electromagnet (130) applies to the control element (110) of the device (100) can be transmitted to the control element (110) nearly without loss. The proposed device (100) is suitable for use in solenoid valves, current-to-pressure converters, position controllers or control valves in process systems or power plants.
