Steam trap ESH8N
- SCCV system
- Suitable for condensate recovery
- Horizontal installation
- Option
- Customized flange
- ASTM material available
- Awarded in 1978 for outstanding energy savings
Properties
-
No condensate build-up on the primary side
Periodic or continuous condensate drainage, depending on the amount of condensate, ensures that the condensate does not accumulate on the primary side.
-
Outstanding durability
The SCCV system valve and the robust lever, as well as the internal components made of stainless steel, ensure outstanding durability of the steam trap.
-
Easy maintenance
This model can also be repaired built-in and is therefore quick and easy to maintain.
-
Condensate recovery
With its high back pressure tolerance, this model is suitable for condensate return at a pressure of up to 90 % of the inlet pressure.
-
Completely closed
The double steam separation mechanism (channel with U-profile and inverted bucket float) ensures reliable steam separation and guarantees the tightness of the steam trap.
-
No vapor or air entrapment
Thanks to a small ventilation opening in the upper part of the bell float, this model does not trap steam or air.

* SCCV system” is the abbreviation for “Self Closing and Centering Valve System”.
Typical applications
- Suitable for use in a wide range of sectors such as agriculture, food production, dyeing, cleaning and air conditioning.

- For reasons of clarity, bypass pipes, valves and other components are not shown.
- For condensate recovery, fit a non-return valve (CV model) and a shut-off valve on the outlet side of the condensate drain.
