A Single Orifice Float Trap (SOFT) is a type of steam trap used in steam systems to discharge condensate and non-condensable gases while preventing the escape of steam. The “Single Orifice” design indicates that it features one orifice for condensate discharge.

Here are some key characteristics and functions associated with Single Orifice Float Traps:

1. Orifice Design: Unlike the Two Orifice Float Trap (TOFT), which has two orifices, the Single Orifice Float Trap has a single orifice for the discharge of condensate. This design simplifies the trap mechanism.

2. Float Mechanism: Similar to other float traps, the Single Orifice Float Trap contains a float mechanism, often a ball float. As condensate accumulates, the float rises, opening the orifice and allowing condensate to be discharged.

3. Continuous Operation: Float traps, including SOFT, operate continuously, discharging condensate as it is formed. This continuous operation helps maintain efficient heat transfer in the steam system.

4. Air Venting: The trap is designed to vent air and non-condensable gases efficiently, preventing their accumulation in the steam system. This is important for maintaining optimal heat transfer and preventing damage to equipment.

5. Application: Single Orifice Float Traps are used in various industrial applications where the removal of condensate and air from steam systems is essential. They are suitable for applications with varying loads and steam pressures.

6. Durability and Low Maintenance: Float traps, including SOFT, are generally known for their durability and low maintenance requirements. Regular inspection and testing are recommended to ensure proper operation.

When considering the installation of a Single Orifice Float Trap (SOFT) or any steam trap, it is important to consider factors such as system pressure, condensate load, and the specific requirements of the application. Always refer to the manufacturer’s documentation and guidelines for accurate information on a particular SOFT model
