Applications in 石油与天然气
上游——井口和采油树
高压井口隔离阀，用于控制原油和天然气从油藏到地面的流动。耳轴式球阀采用金属阀座，可处理含磨蚀性砂粒流体和含硫化氢（H2S）的酸性气体。符合API 6A井口设备标准，PSL 2-3规格等级。
中游——管道和码头
长距离输气管道需要双阻断泄放（DBB）阀，用于管段隔离、清管器收发器隔离以及计量站旁路。全通径设计便于管道内检测（清管）。采用焊接阀体的API 6D管道阀可最大限度地减少泄漏路径。
下游——加工和精炼
炼油厂工艺装置，包括原油蒸馏、催化裂化和加氢处理，需要使用能够处理高温烃类、氢气和腐蚀性酸性水的阀门。闸阀用于隔离，截止阀用于节流，控制阀用于自动化过程控制。
海上平台和FPSO
海上平台和FPSO船舶需要结构紧凑、重量轻且符合防火认证（API 607/6FA）的阀门设计。顶部入口球阀无需从管道上拆卸即可进行在线维护。全焊接DBB阀可消除危险海上环境中阀体接头处的泄漏。
