石油天然气储运工程中，沉淀塔是最为关键的反应容器，沉淀塔能将原料转换为工艺需要的产品，沉淀塔是将白水回收设备和废水的最终处理。所以斜板、斜管沉淀器克服了传统的锥形沉淀塔存在的沉降效率低、容积大，造价高等弱点，成为现代高效的沉淀装置。欧拉姆为国内的环保企业每年供应超2000台大口径球阀。
大口径球阀主要用于火力发电厂各种系统的管道中，用于阻塞或连接管道介质。适用介质：非腐蚀性介质，例如水或蒸汽。与其他阀产品相比，大口径球阀具有高温和高压特性，独特的自密封设计使密封件在较高压力下更加可靠。由于其特殊的性能，技术特性和工作条件，该产品具有其他产品无法替代的特性。
大口径球阀的阀盖与阀杆之间的密封处装有金属动密封装置，阀座与阀体之间的密封处装有弹性浮动密封装置。其金属密封装置由C形弹簧圈和金属弹簧密封套组成。初始密封是通过装配过程中的干涉和挤压实现的。当阀腔介质载荷作用其上时，C形弹簧圈和金属弹簧密封套变形，实现高压密封。
大口径球阀的金属密封装置可以提高阀杆处的密封性能，延长阀门的使用寿命。大口径球阀还配有弹性浮动密封装置，主要由整体碟簧组成。利用碟簧的预紧实现初始低压密封，借助阀腔内的高压介质推动阀座实现高压密封。浮动密封简化了阀座的加工，便于组装和维护。
大口径球阀流体阻力小，是所有阀类中流体阻力最小的一种，启闭迅速方便，以压缩空气为动力，通过活塞齿条，齿轮的机械传动阀杆，以角行程输出的扭矩转动球体 0~90°，就能快速完成启闭动作或调节动作。球芯通道平整光滑，不易沉积介质，可以进行管线式通球。结构简单、重量轻、密封性能好。是自动化控制系统中仪表的执行单元。
紧密可靠，大口径球阀的密封面材料广泛使用塑料、密封性好，在真空系统中也已广泛使用。在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。
工作温度为+ 120°C至-196°C。大口径球阀广泛用于极低温和低温应用，包括但不限于液化天然气，工业气体，精神和钢铁服务，采矿，制药，污水，水处理，二氧化碳注入/混合，冷却和石油/天然气应用。
