ARI-CONA B AWH (PN320 / PN400 / PN630)

Bimetallic steam trap

Description

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

Scope of application
Bimetallic steam traps with thermal controller 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

For regulation the steam trap uses both condensate temperature as well as available upstream pressure and back pressure.
As the temperature of the medium rises the bimetallic plates (pos. 24.6) arch, automatically reducing valve lift.
An intermediately mounted compression spring (pos. 24.5 only required for PN16-100 / Class 150 – 600) also influences valve lift in the lower pressure range, so that when acting together with the bimetallic plates (Pos 24.6) the controller always opens and closes a few degrees below the upstream pressure boiling temperature.
A pendulum-form support (pos. 24.7) for the valve spindle (pos. 24.3) ensures consistent operation, irrespective of the position in which the steam trap is mounted.
The steam trap vents air automatically during system start-up and operation.
The steam trap has a corrosion-resistant, water hammer-proof bimetallic controller, nonreturn protection, and a factory setting for average condensate sub-cooling of approx. 15K (PN16-40 / Class 150 – 300) to approx. 30K (PN63-630 / Class 400 – 2500).
The built-in controller is marked on the type plate as well as on the securing component
(pos. 24.7).

The capacity chart shows the maximum capacity at factory setting.

(For operating pressures below 15 bar, a correction of the factory-setting acc. to manufacturers information is recommended.) Curve 1: Maximum flow of hot condensate at approx. 10 K below saturation temperature.

Curve 2: Maximum flow of sub-cooled condensate at approx. 30 K below saturation temperature (with back-up of condensate). Curve 3: Maximum flow at cold condensate at about 20°C (during start-up of a cold installation).

The condensate temperature determines the opening of the controller. Capacity is increased with the sub-cooling temperature of the condensate.
