Steam trap ES5
- SCCV system
- Suitable for condensate recovery
- Horizontal installation
- 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
- Particularly compact and lightweight, suitable for air conditioning systems and devices, cleaning devices, dyeing devices and similar applications.

- Max. permissible pressure (PMA): 16 bar – PMA is the design pressure of pressure-resistant parts (housing).
- Max. permissible temperature (TMA): 350 ℃ – TMA is the design temperature of pressure-resistant parts (housing).
- Min. operating differential pressure (⊿PMN): 0.1 bar – ⊿PMN is the minimum operating differential pressure between the inlet and outlet of the steam trap.

- 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.
