ARI-CONA 645/647

Condensate discharge temperature limiter (AWH) PN40

Description

eClass-No.: 37010790
Application: for the discharge of condensate without re-evaporation
Medium: Steam, condensate, etc.

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 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

(refer to Fig. 3)
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.
