Abstract: An application device for applying a flowable medium onto a substrate, having a discharge valve having a closure member which, in its open position, releases a metering opening of the discharge valve, such that the flowable medium can flow through the metering opening in the direction of the substrate, wherein the closure member is movable by an electromagnet of the discharge valve from a closing position, in which it closes the metering opening, to an open position, and having a main control unit, which is connected to the discharge valve, and which delivers electrical output voltage signals which moves and maintains the closure member to the open position. A modification unit is arranged between the main control unit and the discharge valve, which is configured such it receives output voltage signals from the main control unit, modifies these signals and relays the latter in a modified form to the electromagnet.

Abstract: A valve arrangement for applying flowable medium to a substrate, in particular hotmelt adhesive, which valve arrangement has a distribution element and a heating device, the heating device being arranged outside the distribution element and being fastened, preferably detachably, as a unit to the distribution element.

Abstract: A valve for flowable media having a valve housing and an elongate closure member arranged therein and which can be axially moved in a medium channel of the valve by a controllable actuator and which in a closed position abuts a valve seat and closes a discharge opening connected to the medium channel, and which is connected to a sealing element to seal the medium channel, namely, a part-piece of an elongate bellows, which moves in an axial direction during movements of the closure member and which is a hollow member made of metal, wherein another part-piece of the bellows is fixedly supported in the valve. The relative axial position between the bellows and the valve seat is adapted to a production-related deviation of the longitudinal dimension of the bellows used from a desired longitudinal dimension so that this deviation is compensated for.

Abstract: A valve arrangement for applying flowable medium to a substrate, having a main valve body with a medium channel for flowable media which is able to be closed by a movable closure member and to which a nozzle part having a nozzle opening of the valve arrangement is connected, wherein the valve arrangement has a pivotable lever movable out of a fastening position and into a releasing position, wherein the pivotable lever, during the movement from the fastening position into the releasing position, exerts a detaching force on the nozzle part in order to support the detachment of the nozzle part from the main valve body. In a first phase of its movement out of the fastening position and into the releasing position, the lever is movable in a straight line and exerts the detaching force on a push-off surface of the nozzle part, and entrains the nozzle part.

Abstract: A valve for free-flowing media, such as a glue valve, with a valve housing, and with a closure member, such as a valve tappet, which is movable in the valve housing by means of an electromagnet and which bears with a closure piece on a valve seat in the closed position of the valve and which sits at least partially in a continuous interior of a one-piece coil carrier on which the windings of a coil of the electromagnet are wound, and having two terminal receivers for a dosing unit and a valve lift adjustment unit with an elongate abutment part which is arranged at least in part in the interior of the coil carrier and which limits a movement of the closure member in the direction of the valve lift adjustment unit, with the valve lift adjustment unit being is secured on the coil carrier.

Abstract: A glue valve arrangement having a controllable, in particular electromagnetically operated metering member for the delivery of glue, having a main body with glue duct leading to the metering member, having a tubular glue line, with which glue originating from a separate glue source can be fed to the glue duct, having a rotary feedthrough, detachably fastened to the main body, for the articulated connection of the tubular glue line to the main body, and having a filter for the filtering of the glue. The invention is characterized in that the filter is assigned to the rotary feedthrough.

Abstract: A modular valve for free-flowing media, with a main module with a valve housing and an electromagnet, a dosing module with a closure member which is movable by means of the electromagnet and which closes a dispensing opening of the dosing module, and a valve lift adjustment module for adjusting the valve lift, which valve lift adjustment module comprises an elongate abutment part which is arranged at least in part in a valve interior of the main module and is modifiable in its axial position in the valve interior, which abutment part limits the movement of the closure member in the direction of the valve lift adjustment module, the dosing module and the valve lift adjustment module being connected releasably to the main module in such a way that the dosing module and the valve lift adjustment module can each be replaced by another module of the same module type.
