M - Thermostatic steam traps
4.0 Description
4.1 Scope of applications
Thermostatic steam traps with thermal controller 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
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.
Four capsule types are available with different discharge temperatures:
The controller designation and capsule type are stated on the type plate
Series 610/612; 611/613:
The seat assembly has a fast-acting non-return safety feature and a downstream blast
device which minimises body erosion caused by outflowing condensate (not for controller
R5).
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.
Capsule Discharge temperature
No 1 approx. 3-5 Kelvin (for controller R5 only)
No. 2 approx. 10 Kelvin below boiling temperature
No. 3 approx. 30 Kelvin below boiling temperature
No. 4 approx. 40 Kelvin below boiling temperature
(not for type B) (refer to item 7.3)
