Thermostatic Steam Trap is an all-stainless-steel thermostatic steam trap that discharges condensate and air from steam lines. Its thermostatic capsule follows the steam saturation curve: it opens when condensate cools and closes when steam arrives.

How Does It Work?
When the system is cold, the capsule is open and air and cold condensate are discharged quickly. As condensate approaches steam temperature, the capsule expands and closes. It discharges continuously or intermittently depending on the condensate load.
Applications
- Irons and ironing presses
- Drying units
- Pressing units
- Steam-jacketed pipes
- Air venting in steam lines
Key Features
- All stainless steel, long life in corrosive conditions
- Not affected by water hammer
- Vents non-condensable gases
- Easy maintenance
Selection and Installation
Size a steam trap by condensate load and differential pressure, not by pipe size. The flow direction is marked on the body.
