Abstract: A device for a valve in process fluid technology includes a sealing element which interacts with a movable shut-off body of the valve or itself provides the shut-off body, and which comprises a plurality of functional regions. The device includes at least one electrically conductive elastomer portion which is associated with the sealing element and which is assigned, at least in portions, to one of the plurality of functional regions. The device also includes an operating unit which is designed to operate the electrically conductive elastomer portion.

Abstract: A valve diaphragm is provided, comprising: an edge region arranged at a narrow side, in particular a tab protruding beyond a functional region of the valve diaphragm, wherein a recess of the edge region comprises, starting from an opening of the recess, a diameter enlargement; and a plastic body which comprises a transponder and whose fastening portion protrudes through the opening, wherein, by means of a shaping process effected in the diameter enlargement of the recess, in particular by hot caulking, at least one region of the fastening portion at least partially fills the diameter enlargement.

Abstract: A valve diaphragm for a diaphragm valve includes a clamping section aligned with an imaginary vertical plane of an actuation axis, and a functional section surrounded by the clamping section. The functional section includes at least two flexing sections and a web-shaped sealing section that separates the flexing sections and connects two portions of the clamping section. The sealing section is configured to have, at least in part, a greater compressive yield point and/or a smaller compression set in a direction perpendicular to its longitudinal extent than along its longitudinal extent. This directional difference in mechanical properties allows the sealing section to maintain dimensional stability under compressive load while permitting flexibility along its length for improved sealing performance and durability.

Abstract: A valve diaphragm for a diaphragm valve includes a diaphragm layer having a clamping section and a functional section surrounded by the clamping section. The functional section is displaceable along an actuation axis. At least one elastic force transmission element is disposed on or within the clamping section and is structurally separate from the diaphragm layer. The force transmission element is configured to clamp the valve diaphragm against a valve body of the diaphragm valve.

Abstract: A multi-layer valve diaphragm for a diaphragm valve includes a first diaphragm layer configured to contact a process medium and a second diaphragm layer positioned on a dry side of the first layer. The second diaphragm layer includes a bracing section and a functional section that is at least partially surrounded by the bracing section. The bracing section and the functional section are arranged at least partially spaced apart from one another to reduce mechanical coupling between regions subject to static and dynamic stresses. This configuration improves the durability of the valve diaphragm during repeated actuation.

Abstract: A semiconductor power switch comprises at least a first IGBT and a second IGBT. The collectors of the first and second IGBTs are connected to each other, and the emitters of the first and second IGBTs are connected to each other. The first IGBT is an IGBT type with a comparatively low collector-emitter on-voltage and a comparatively high turn-on or turn-off switching energy. In contrast thereto, the second IGBT is an IGBT type with a comparatively high collector-emitter on-voltage and a comparatively low turn-on or turn-off switching energy. Both IGBTs receive gate signals from a control circuit for switching the power switch on during a first time interval and switching the power switch off during a second time interval. The control circuit is designed to supply an on-signal to the second IGBT during the whole first time interval and another on-signal to the first IGBT during only a part of the first time interval, which is less than the whole.

Abstract: In a switching arrangement for controlling a load-controlled power switch via a transformer Ü, a voltage signal is inputted into the transformer, the voltage signal being comprised of impulses of short duration T1p, T1n in positive and negative directions. Two field effect transistors F1, F2 at the secondary side of the transformer Ü convert the impulses T1p, T1n into impulses T3p, T3n in positive and negative directions which reliably control the power switch LT, the impulse duration of the impulses T3p, T3n being extended to the beginning of the next input impulses with reversed voltage directions T1n, T1p. A diode D1 and D2, respectively, is disposed in each of the field effect transistors F1and F2 between the source terminal S and the drain terminal D thereof. A respective series switch is activated ahead of the gate terminals of each respective field effect transistor F1 and F2.
