加氢反应器是有机化学实验室和实际生产过程中一件非常重要的设备，不仅可以用作加氢反应的容器，而且也可用于液体和气体需要充分混合的场合。不锈钢在加氢反应器中起到启闭的作用。欧拉姆的不锈钢闸阀已累计销售出一万多台，质量更可靠更安全更稳定
不锈钢闸阀（gate valve）的启闭件是闸板，闸板的运动方向与流体方向相垂直，不锈钢闸阀只能作全开和全关 , 不能作调节和节流。闸板有两个密封面 , 最常用的不锈钢闸阀的两个密封面形成楔形、楔形角随不锈钢闸阀参数而异 , 通常为 50, 介质温度不高时为 2°52' 。不锈钢闸阀的闸板可以做成一个整 体，叫做刚性闸板；也可以做成能产生微量变形的闸板 , 以改善其工艺性 , 弥补密封面角度在加工过程中产生的偏差 , 这种闸板叫做弹性闸板。不锈钢闸阀材质分为304不锈钢闸阀，316不锈钢闸阀，321不锈钢闸阀。
如果闸阀的闸板与阀杆直线移动，则称为提升杆闸阀（也称为明极闸阀）。提升杆上通常有梯形螺纹，通过阀顶部的螺母和阀体上的导槽将旋转运动变成直线运动，即将操作扭矩变成操作推力。密封面只能通过介质压力密封，即闸门的密封面可以通过介质压力压向另一侧的阀座，以确保密封面的密封，即自密封。大多数闸阀都是强制密封的，也就是说，当阀门关闭时，闸板应通过外力压向阀座，以确保密封面的密封性能。
本体采用高级不锈钢制成，重量较传统闸阀重量减轻约20%~30%，安装维修方便。传统的闸阀往往在通水洗管后即因外物诸如石头，木块、水泥、铁屑、杂物等淤积于阀底凹槽内，容易造成无法关闭紧密而形成漏水现象，弹性座封闸阀底部采用与水管机同的平底设计，不易造成杂物淤积，使流体畅通无阻。
阀体采用精密锻造，精确的几何尺寸使得阀体内部无需任何精加工即可保证阀门的密封性。流体阻力小，密封面受介质的忡刷和侵蚀小。
形体简单，结构长度短，制造工艺性好，适用范围广。开闭较省力。介质流向不受限制，不扰流、不降低压力。
