An operating attachment () for operating a push button or switch, which includes a housing, () a handling part () having an actuator element () supported by said housing () for rotation in a direction of rotation (U), an operating element () displaceable parallel to a longitudinal axis (L) of the housing for operating a push button or switch, an operating drive () for transferring rotary movement of the actuator element () into a linear motion of the operating element () between an initial position (A) and an operating position (B), and a latching device () for latching the actuator element () in a latched position (R). The attachment apparatus () further includes at least one encoding element () moveable between a first encoding position (K) that allows for rotation of the actuator () into the latched position (R) and a second encoding position (K) which limits rotation of the actuator element () prior to reaching the latched position (R). The illustrated encoding element () further is moveable to a third encoding position (K).

A diaphragm valve, in particular for fluid media, includes a valve body, a diaphragm, and a connecting piece which can be actuated by a drive unit to act on the diaphragm, wherein the valve body and the diaphragm are made of plastic. Two mutually independent seals are provided for sealing the fluid medium with respect to the outside, wherein the valve body and the diaphragm are welded to each other, and the diaphragm is mechanically sealed between the drive unit, or an intermediate piece, and the valve body.

Diaphragm valve

Diaphragm valve having a valve body with an inlet and an outlet, a sealing membrane, and a connecting piece connecting the sealing membrane to a pressure piece of a drive. The valve body, the sealing membrane and the connecting piece are rigidly connected together to form an interchangeable, sealed valve body unit that can be connected to the drive. The connecting piece is molded on the sealing membrane, and the valve body and the sealing membrane are welded ultrasonically to one another.

Single use, disposable diaphragm valve in which the valve body and sealing membrane are welded to one another
