Abstract: A dosing method for carrying out at least one dosing operation, including the steps: providing a switching signal to or from a valve control, providing a coil current from the valve control to a magnetic drive in dependence on the switching signal, in which the magnetic drive is configured to move a valve member of a solenoid valve between a normal position and a functional position, determining a first start of movement of the valve member from the normal position to the functional position, determining an operating duration between the provision of the coil current and the first start of movement, determining a providing duration for the switching signal. The provision of the coil current is carried out over a coil current duration which corresponds to a sum of the providing duration and the operating duration.

Abstract: A solenoid valve, including a valve housing with a fluid channel and a valve member located moveably in the fluid channel between a first and a second functional position and a solenoid coil to move the valve member. A valve control provides electrical energy to the solenoid coil and includes a timer, which timer is activated by a first movement signal to the valve control or which timer is activated upon arrival of the valve member in the first functional position. The timer has a first state before a predefined time span has elapsed and the timer has a second state after the predefined time span has elapsed and the valve control interrogates the respective state and provides a first quantity of electrical energy during the first state and provides a second quantity of electrical energy, which is greater than the first quantity, during the second state.

Abstract: A membrane valve, with a valve housing, in which a housing interior is formed, in which housing interior a flexible control membrane is arranged. A drive plunger lies opposite a valve seat and the drive plunger has a shank body with a peripheral outer lateral surface. The outer lateral surface of the shank body of the drive plunger at least in the region of a guide section has a polygonally contoured prismatic shaping with a succession of outer side edges and outer side surfaces, wherein the edges and surfaces extend in the plunger longitudinal direction and the succession alternates in the circumferential direction of the drive plunger.

Abstract: The present invention relates to a sterilizing device (10) and to a method for sterilizing an outer face of a receptacle (22).

Abstract: A diaphragm valve includes a valve housing in which a switching rocker, which is pivotable about a pivot axis and which interacts with a control diaphragm for opening and closing at least one valve channel, is arranged. The pivot axis is defined by a mounting web, on which the switching rocker bears in a pivotably movable manner. The mounting web is an integral constituent of a mounting unit, said mounting unit being fastened to the valve housing in a drive chamber by way of fastening measures. Without the fastening measures, the mounting unit can be displaced in order to adjust a desired height distance of the mounting web.

Abstract: A diaphragm valve has a valve housing and a valve member movable relative to said housing. The valve member includes a diaphragm carrier that can be driven to execute a switchover motion having a sealing diaphragm mounted thereon, which delimits a valve chamber in which a valve seat is found. The sealing diaphragm has a sealing section opposite said valve seat belonging at least partially to a loose diaphragm section of the sealing diaphragm, which can lift from the diaphragm carrier to reduce the stress on the sealing diaphragm when said diaphragm carrier is removed from the valve seat during switching.
