Condensate discharge temperature limiter
4.0 Description
4.1 Scope of applications
Condensate discharge temperature limiters with temperature control are used for the
discharge of condensate without flashing.
The information complies to the Pressure Equipment Directive 97/23/EC.
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.
4.2 Operating principles
(refer to Fig. 3 page 7)
For control the condensate discharge temperature limiter uses the set discharge
temperature as well as existing upstream pressure and back pressure.
The controller is adjustable from 60°C to 140°C.
In the cold state the valve is fully open, thus giving automatic start-up venting and maximum
throughput.
As the temperature of the medium rises the bimetallic discs (Pos. 24.6) arch, automatically
reducing the valve stroke.
The controller (Pos. 24) closes when the set discharge temperature is reached.
The steam trap has a corrosion-resistant, water impact-insensitive bimetallic controller,
non-return protection, and a factory setting for condensate sub-cooling of approx. 10 K
below opening temperature.
ATTENTION !
- Refer to the data sheet for applications, limits on use and possibilities.
- Certain media require or preclude the use of special materials.
- The valves are designed for standard operating conditions. If conditions exceed
these requirements, e.g. aggressive or abrasive media, the operator should
state the higher requirements when ordering.
- Valves made from grey cast iron are not authorised for use in systems subject
to TRD 110.
