A valve plate has a plate portion with an elastomeric seal on a front face and an elongated connecting portion spaced apart from a rear face by a slot for fastening the valve plate to a valve rod. The extension of the connecting portion in the width direction is defined by opposing first and second side edges of the connecting portion when viewed in a plan view of the rear face of the plate portion. A connecting structure is configured in the connecting portion in a central region of the longitudinal extension of the first side edge of the connecting portion for connecting the connecting portion to an end portion of the valve rod. The connecting portion is reinforced in a region of its extension in the width direction adjoining the second side edge, relative to a region of its extension in the width direction adjoining the first side edge.

Valve plate

A valve plate has a plate portion with a front side elastomeric seal fitted thereon, and a connection apparatus arranged at the rear side for connecting the valve plate to a carrier apparatus of a vacuum valve. The connection apparatus includes first and second elongate connection portions, the first connection portion is located at one side and the second connection portion is located at the other side of the longitudinal center of the plate portion, with each being connected to the plate portion with the two spaced-apart ends thereof. The connection portions are spaced apart from the plate portion in the region between the two ends thereof, with a respective slot formed between the plate portion and the respective connection portion, and have in a central region of the longitudinal extent thereof a connection structure for connection to an end portion of a respective valve rod of the carrier apparatus.
