蒸汽疏水阀的作用是自动排除加热设备或蒸汽管道中的蒸汽凝结水及空气等不凝气体，且不漏出蒸汽。由于疏水阀具有阻汽排水的作用，可使蒸汽加热设备均匀给热，充分利用蒸汽潜热防止蒸汽管道中发生水锤。
FLT14I float and thermostatic (integral air vent) steam traps series are designed for all types of low and high pressure steam heating and process equipment.
Typical applications include unit heaters, heat exchangers, driers, jacketed vessels and all the applications where continuous drainage is essential.
Connections are female screwed or flanged for horizontal or vertical installation.
Main Features
•Modulating discharge.
•Discharges condensate at steam temperature.
•Unaffected by sudden or wide load and pressure changes.
•Excellent air discharge (by thermostatic air vent).
