Page 2: Usage Of The Product
1. Usage of the product The TSF-8 can discharge condensate effectively without retention, and realize energy saving steam system without steam loss. In addition, built in thermostatic air vent discharges air inside the piping and shortens warming-up time. So, the product is suitable for steam equipments used in various industries such as air-conditioning equipment, hot-water supply equipment, plant, and food. -

Page 4: Operation
4. Operation Air vent Float 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. -
Page 5: Maximum Continuous Discharge Capacity
5. 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. If inlet pressure is 0.5 MPa and outlet pressure is 0.2 MPa, discharge capacity is of working differential pressure of 0.3 MPa. -
