Applications in 发电
主蒸汽和再热系统
主蒸汽管道将温度为540-565℃、压力为170-250巴的过热蒸汽从锅炉输送至汽轮机。柔性楔形闸阀用于在启动和维护期间隔离锅炉各段。截止阀控制减温器喷水，以调节蒸汽温度。铬钼合金钢（WC6/WC9）可承受热循环而不发生蠕变性能退化。
给水和凝结水
锅炉给水泵通过给水控制阀向锅炉输送高压水。这些球形控制阀在运行过程中会经历严重的汽蚀和闪蒸。采用多级泄压的防汽蚀阀芯设计可以延长阀门的使用寿命。冷凝水抽取泵使用带有低压弹簧的止回阀。
冷却水和循环水
直流和循环冷却水系统采用大直径蝶阀（24-72英寸）进行流量隔离。橡胶衬里或环氧涂层阀门可抵抗微咸水或海水冷却中的腐蚀。冷凝器管束需要隔离闸门以便于清洁和维护。
烟气脱硫（FGD）
湿式脱硫装置利用石灰石浆液从锅炉烟气中去除二氧化硫。浆液阀用于处理具有磨蚀性的石灰石和石膏混合物。常用的阀门是橡胶衬里蝶阀和夹管阀。为了隔离出口，双耳蝶阀可实现与腐蚀性饱和烟气的完全密封。

Cavitation and Noise in Control Valves
Control valves operating at high pressure drops face two destructive forces: cavitation and fluid-dynamic noise. Both stem from the same physics — pressure falling below the fluid's vapor pressure at the vena contracta — but they manifest differently and require distinct mitigation strategies. Corre
