Description
Application: | For discharge of condensate with limited sub-cooling |
Medium: | Steam, condensate, etc. |
Scope of applications
Thermodynamic steam traps 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.
Operating principles
Series 640/641:
(refer to Fig. 1-Fig. 2, -Fig. 3)
For control the steam trap uses the condensate temperature as well as the available
upstream pressure and back pressure.
In the controller (Pos. 24) the valve plate (Pos. 25) is enclosed by the cap and the seat.
When the boiling temperature of the medium is reached, a cushion of steam forms over the
valve plate (Pos. 25) and presses the valve plate (Pos. 25) onto the seal faces of the seat.
To a very great extent the external sealing cap (Pos. 6) frees the steam trap (in PN40 /
Class 150 / Class 300) from environmental influences. The steam cushion collapses as a
result of condensate formation and the associated temperature drop.
The system pressure lifts the valve plate (Pos. 25) from the seat face. The steam trap
opens and removes condensate.
The steam trap vents air automatically during system start-up and operation, but with a time
lag. The steam trap acts as a non-return valve.
The built-in controller is marked on the type plate.
