Ball float steam traps

Application: For discharge of condensate at boiling temperature
Medium: Steam, condensate, gases with liquid components, etc.

Scope of application
Float-type steam traps with level control and thermal regulation are used for the drainage of industrial steam facilities.

The information complies to the Pressure Equipment Directive 2014/68/EU.
It is the responsibility of the machine planner to ensure compliance.
The special markings on the valve must be taken into account.
Refer to the catalogue sheet to see which materials are used in standard versions.
Please contact the supplier or the manufacturer if you have any questions.

The steam trap is controlled by a swivel-mounted ball float (Pos. 24.16).
An integral bimetallic element (Pos. 24.6) provides automatic starting ventilation in the cold state.
At temperatures less than 90°C, the bi-metallic element holds the discharge orifice open, allowing air and other gasses to escape. At 90°C the bi-metallic element is fully closed and discharge is controlled only by the float mechanism (Pos. 24.16).
At the higher temperatures, air is automatically evacuated (Pos. 24.12), ejector style, with the condensate.
If the amount of condensate decreases or if there is no condensate, the ball float (Pos. 24.16) faces and locks the valve ball (Pos. 24.4) on the seat (Pos. 24.1). If the steam trap is acted upon only by vapour, the condensate-flooded seat (Pos. 24.1) remains shut.
The valve ball (Pos. 24.4) also works with the seat (Pos. 24.1) as a non-return valve.

The capacity chart shows the maximum flow quantities of hot condensate for the different controllers and steam trap sizes

In commen, the steam traps are fitted out with an controller as shown in the flow diagrams of this page acc. to the differential pressures and flow rates.

For very large flow rates with low differential pressures, steam traps at sizes DN40 up to DN100 can be fitted out with a super-controller

The maximum flow quantity of cold condensate at about 20°C can be determined by multiplication of the appropriate factor F (in the scale below the diagrams) with the hot condensate quantity determined by the capacity chart. (Factor F is related to the differential pressure)
