ARI-CONA® SC Plus (AWH)

Ball float steam traps

Description

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.

Operating principles

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.

Welding groove acc. to DIN 2559

The material used for ARI valves with butt weld ends are: 1.0460 P250GH acc. to DIN EN 10222-2

Note: 1.4541 X6CrNiTi18-10 acc. to DIN EN 10222-5 Note restriction on operating pressure / inlet temperature depending to

design!

Due to our experience, we recommend to apply an electric welding process.

Because of the different material compositions and wall thickness of the steam traps and the pipe gas welding shall not be applied. Quenching cracks and coarse grain structure may develop.

Steam traps with socket-weld ends shall only be welded by arc welding (welding process 111 acc. to DIN EN 24063).

If during the time of warranty others than the manufacturer or by the manufacturer authorized persons are interfering in the product and/or the setting, the right of claim for warranty will lapse!
