The Yoshitake TSF-11 is a float-type steam trap equipped with an incorporated thermostatic air vent. It is designed to discharge steam condensate effectively without retention, realizing an energy-saving steam system without steam loss. The incorporated thermostatic air vent discharges air inside the piping and significantly shortens warming-up time.

By turning the cock, the flow direction can be switched easily to accommodate horizontal or vertical installations without disassembling the cover. Since all main parts are installed on the cover, inspection and parts replacement can be conducted easily with the body remaining installed on the piping.

Features

• Discharges condensate effectively without retention to minimize steam loss.
• Incorporated thermostatic air vent shortens warming-up time.
• Flow direction can be switched easily by turning the cock without disassembly.
• Main parts are installed on the cover, allowing easy inspection and parts replacement on the piping.

Caution for Installation

Adjust the direction of the nameplate in a no-pressure condition after installation.

Fix the cock with a spanner and loosen the nut. Turn the cock and adjust the direction of the nameplate to position the "TOP" and "BOTTOM" signs upside and downside respectively. Fix the cock with a spanner and fasten the nut after adjustment.

WARNING

In case of a bottom-to-top flow, please shorten the vertical piping before the trap to allow it to open and discharge easily when using an upward flow direction.

Maximum Continuous Discharge Capacity

TIP

The discharge capacity shown in the chart above is the maximum value. When designing a system, select a steam trap with a sufficient safety factor (more than two times the regular level).
