A vacuum valve system (10) is provided that includes a valve seat mechanism having a valve opening, a first valve seat surrounding the valve opening, and a second valve seat surrounding the valve opening, a closing part (20) for closing the valve opening substantially in a gas-tight manner and having a first sealing surface and a second sealing surface; and a drive unit for providing a movement of the closing part (20) relative to the valve seat mechanism such that the closing part (20) can be moved from an open position in a closing direction into a closed position and a counter-movement. The closing element (20) has a first closing side (24) with a first sealing surface and a second closing side (25) with a second sealing surface. The closing element (20) has a closing body (23) which is arranged between the first closing side (24) and the second closing side (25) and connects them. The closing body (23) and the closing side (24, 25) are designed in such a way that the closing part (20) has at least one first recess which is open towards the edge of the closing part (20), and at least the opening of the first recess faces the closing direction.
提供了一种真空阀系统(10),包括阀座机构,其具有阀开口、围绕阀开口的第一阀座和围绕阀开口的第二阀座,用于基本上气密关闭阀开口的且具有第一密封面和第二密封面的关闭部件(20)和用于提供关闭部件(20)相对于阀座机构的运动以致关闭部件(20)能从打开位置沿关闭方向运动到关闭位置和反向运动的驱动单元。关闭部件(20)具有带有第一密封面的第一关闭侧(24)和带有第二密封面的第二关闭侧(25)。关闭部件(20)具有布置在第一关闭侧(24)和第二关闭侧(25)之间且连接它们的关闭体(23)。关闭体(23)和关闭侧(24,25)被设计成关闭部件(20)具有至少一个朝向关闭部件(20)边缘敞开的第一凹部,并且至少第一凹部的开口朝向关闭方向。
