Abstract
A valve has a valve housing with a first port and a second port, and has a closing member movable along an axial direction. When in a closed position, the closing member interacts sealingly with a valve seat to block a fluid connection between the first and second ports. An fluid-impermeable diaphragm comprises a central opening through which a closing member arrangement including the closing member extends, and a clamping section that runs in a clamping gap. The diaphragm is held with sealing action between the closing member arrangement and a holding arrangement on the housing. The diaphragm has a first section and a second section adjoining the first section. The first section is held in the holding arrangement with a force fit, the second section is guided in the holding arrangement, and the first and second sections are arranged at an angle relative to one another. A form fit is generated by the first section, second section and holding arrangement.
