Overview
双金属式蒸汽疏水阀会在低于饱和温度的条件下排放冷凝水，因此可以回收冷凝水中的部分显热。这使它非常适合那些允许或有利于过冷排放的工况。 它属于最坚固的热静力蒸汽疏水阀设计之一，对水锤和腐蚀性冷凝水都有较强承受能力。 该系列覆盖较宽的压力和负荷范围，具备良好排空气能力，可减少二次蒸汽损失，并采用针对不同排量需求设计的双金属元件。 当耐久性和冷凝水冷却价值比“在蒸汽温度下立即连续排凝”更重要时，它通常会被优先考虑。 在更高压力工况中，如果用户更偏好比轻型热静力方案更坚固的机构，双金属式疏水阀也很有价值。
相关过冷排放路径
双金属式疏水阀通常用于“坚固的热静力性能和过冷排放更重要”的场合。如果应用更依赖较强排空气能力和随压力变化自动响应的特性，可比较压力平衡式蒸汽疏水阀。如果项目需要固定预设排放点，也可同步比较固定排放温度疏水阀。

Continue your bimetallic trap selection
Bimetallic steam traps are usually chosen when the application benefits from sub-cooling and the user wants a more rugged thermostatic design.
Compare the wider trap portfolio
Return to the wider steam traps range when you need to compare bimetallic traps with balanced pressure, thermodynamic or mechanical trap families.
Compare thermostatic trap behaviour
Use balanced pressure traps when strong air venting and pressure-responsive thermostatic behaviour matter more than the rugged bimetallic format.
Check application fit before final selection
Review trap selection guidance when the main question is whether sub-cooling is acceptable for the duty before choosing the trap family.
