4.0 Description
4.1 Scope of applications
CONA Universal Steam traps for quick assembly/disassembly to CONA Connector or
foreign system connectors are used for the drainage of industrial steam facilities.
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
4.2.1 CONA Universal
a) Bimetallic steam trap BR604
(refer to Fig. 1 page 6)
(detailed description of the control system Operating and installation instructions CONA B
BR600)
For regulation the steam trap uses both condensate temperature as well as available
upstream pressure and back pressure.
The steam trap vents air automatically during system start-up and operation.
The steam trap has a corrosion-resistant, water hammer-proof bimetallic controller, non-
return protection, and a factory setting for average condensate sub-cooling of approx. 15K
(PN16-40)
b) Thermostatic steam trap BR622
(refer to Fig. 2 page 6)
(detailed description of the control system Operating and installation instructions CONA M
BR610)
The steam trap uses the condensate temperature and available upstream pressure for
control. It vents automatically during system start-up and operation. It has a corrosion-
resistant, water hammer-proof diaphragm capsule which always discharges the
consistently supercooled condensate a few degrees below the upstream pressure-
dependent boiling temperature (ca. 10K).
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.
