MODEL SJ6FX

SDS U2000-140

Inline repairable multi-purpose steam trap with tight shut-off for use with heat exchangers,tank heaters, dryers and process equipment.1. Thermostatic X-element with fail-open

feature vents air automatically at close-to-steam temperature.

2. Only one moving part, the free float, eliminates concentrated valve wear andprovides long maintenance-free service life.

3. Easy, inline access to internal parts simplifiescleaning and reduces maintenance cost.

4. Two built-in screens with large surface areaensure extended trouble-free operation.

5. Self-modulating free float provides con-tinuous, smooth, low velocity condensatedischarge as process loads vary.
