冷却系统按照冷却介质不同可以分为风冷和水冷。如果把发动机中高温零件的热量直接散入大气而进行冷却的装置称为风冷系统。而把这些热量先传给冷却水，然后再散入大气而进行冷却的装置称为水冷系统。由于水冷系统冷却均匀，效果好，而且发动机运转噪音小，目前汽车发动机上广泛采用的是水冷系统。欧拉姆阀门的低温闸阀能够在冷却系统中有效稳定的运行，质量好使用期限长，一对一针对设计。
长期以来市场上使用的低温闸阀普遍存在着漏水或生锈现象，本企业引进高科技低温闸阀制造技术所生产的弹性座封闸阀，克服了一般低温闸阀密封不良，生锈等缺陷，弹性座封闸阀利用弹性闸板产生微量弹性变形的补偿作用达到良好的密封效果，该低温闸阀具有开关轻巧、密封可靠、弹性记忆佳及使用寿命等显著优点。可广泛用于自来水、污水、建筑、石油、化工、食品、医药、轻纺、电力、船舶、冶金、能源系统等体管线上作为调节和截流装置使用。
低温闸阀的启闭部件是闸阀，闸阀的运动方向垂直于流体方向。闸阀只能完全开启和关闭，但不能调节或节流。浇口有两个密封面。最常用的闸阀的两个密封面形成楔形。楔角随阀门参数而变化，一般为50°，介质温度不高时为2° 52′。楔式闸阀的闸板可以做成整体，称为刚性闸板；也可以做成能产生轻微变形的浇口，以提高其工艺性，弥补加工时密封面角度的偏差。这种闸门称为弹性闸门。
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。
