A reliable and durable free float steam trap with tightshut-off for use on medium-size process equipment.1. Self-modulating free float provides continuous, smooth,

low velocity condensate discharge as process loadsvary.

2. Constant water-seal design ensures steam-tight seal,even under low-load conditions.

3. Only one moving part, the free float, eliminatesconcentrated valve wear and provides long maintenance-free service life.

4. Thermostatic capsule (X-element) with fail-openfeature vents air automatically until close-to-steamtemperature for rapid start-up, increased productivityand even heating.

5. Easy, inline access to internal parts simplifies cleaningand reduces maintenance costs.

6. Built-in screen with large surface area ensures trouble-free operation.

Discharge Capacity

1. Line numbers within the graph refer to orifice numbers.2. Differential pressure is the difference between the inlet and outlet pressure of the trap.3. Capacities are based on continuous discharge of condensate 6C below saturated steam temperature.4. Recommended safety factor: at least 1.5.

DO NOT use traps under conditions that exceed maximum differential pressure,as condensate backup will occur!CAUTION
