The invention relates to a valve (100) having a valve housing (160), which has a first port (102) and a second port (104), having a closing member (106), which is movable along an axial direction and which can be placed into a closed position in which the closing member (106) interacts sealingly with a valve seat (108) arranged between the first port (102) and second port (104), whereby a fluid connection between the first and second ports (102, 104) is blocked, and having a diaphragm (200) which is impermeable to fluid, comprises a central opening (212) through which a closing member arrangement (126) comprising the closing member (106) extends, comprises a clamping section (206) which runs in a clamping gap oriented obliquely with respect to the axial direction, and is held with sealing action at one side on the closing member arrangement (126) and at the other side on a holding arrangement (120) on the valve housing. To provide a valve that has a reduced need for maintenance, it is proposed that the diaphragm (200) has a first section (202) situated at an outer edge and has a second section (204) adjoining the first section (202) radially to the inside, that the first section is held in the holding arrangement with a force fit, that the second section is guided in the holding arrangement, and that the first and second sections (202, 204) are arranged at an angle (V) with respect one another and the holding arrangement is configured such that a form fit is generated by the first section (202), second section (204) and holding arrangement (figure 2). The invention also relates to a diaphragm for a valve. |
