Applications in 水处理
海水淡化（反渗透和热法）
反渗透海水淡化装置使用高压进料泵（60-80巴），因此需要采用耐腐蚀的双相不锈钢或超级双相不锈钢阀门。热法海水淡化（MSF/MED）使用大直径蝶阀进行浓盐水循环和馏出液冷却。环氧涂层或橡胶衬里的阀门可防止海水环境下的缝隙腐蚀。
污水处理厂
市政和工业污水处理厂处理原污水、活性污泥和处理后的出水。刀闸阀用于隔离渠道和池中的工艺流程。旋塞阀用于处理砂砾和浮渣。曝气系统采用微泡扩散器控制阀。耐腐蚀涂层和全通径设计可防止固体堵塞。
饮用水分配
饮用水处理和分配需要使用符合NSF/ANSI 61认证的无铅阀门。弹性密封闸阀用于隔离分配段。止回阀可防止回流污染。排气/真空破坏阀可保护管道免受浪涌损坏和真空崩溃的影响。
工业废水和化学处理
采矿、电镀和化工厂产生的工业废水含有重金属、酸和碱，需要进行中和处理。化学加药系统采用聚四氟乙烯（PTFE）衬里的球阀进行酸/碱注入。澄清池底流采用耐磨刀闸阀进行污泥排出。

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
