Yoshitake TSF-10 and TSF-10F are float steam traps featuring an incorporated thermostatic air vent. By turning the cock, the product can be installed in various flow directions such as horizontal or vertical piping without disassembly. Since all main parts are mounted on the cover, inspection and parts replacement can be easily conducted without detaching the valve body from the pipeline.

Features

• The TSF-10·10F·11·11F can discharge condensate effectively without retention, and realize energy saving steam system without steam loss.
• Incorporated thermostatic air vent discharges air inside the piping and shortens warming-up time.
• By turning the cock, it is possible to meet various flow direction such as horizontal or vertical installation. Flow direction can be switched easily without disassembly such as detaching the cover.
• Since the main parts are installed on the cover, it is possible to disassemble the cover with the body installed on the piping so the inspection and parts replacement can be conducted easily.

Operation

1. Start-up of the operation At start-up, since the float is down, the valve is closed. In this state, air in the system and piping is discharged out through the air vent which is opened. When condensate flows into the product, the float lifts up and opens the valve, and then discharges condensate. Air is continuously discharged out from the air vent.

2. Condensate discharging operation When steam flows into the product, internal pressure of the air vent rises by steam temperature, and the air vent closes. According to the amount of condensate inflow, the float position moves up and down changing the opening degree of the valve, and thus condensate is continuously discharged. The float moves down and the valve closes when condensate inflow stops.

3. Air vent operation When air or non-condensable gas flows into the product, it accumulates in the upper part of the product. When temperature of air or noncondensable gas decreases with condensate inflow, the air vent opens and discharges it to outside of the product. Then, operations 2 and 3 repeats according to the inflow amount of condensate and air.

Maximum Continuous Discharge Capacity

1. Discharging capability of the steam trap differs by working differential pressure, that is, difference between inlet pressure and outlet pressure (back pressure). In selecting discharge capacity, consider outlet pressure.
2. The discharge capacity shown in the charts below is the maximum value. In designing a system, select a steam trap with a sufficient safety factor (two times the regular level).

Precaution for installation

Adjust direction of the nameplate

Adjust direction of the name plate in no pressure condition after installation. Fix the cock with spanner and loosen the nut. Turn the cock and adjust direction of the name plate to position "TOP" and "BOTTOM" signs on upside and downside respectively. Fix the cock with spanner and fasten the nut after adjustment.

*In case of Bottom to Top, Please apply that shorten the vertical piping before the trap to open and discharge easily of trap in the condition of using upward flow direction.
