Steam trap TBU4-SR
- SCCV system
- Stainless steel
- Suitable for condensate recovery
- Horizontal installation
- Vertical installation
- Bypass function
- Automatic venting
-
Scale can be removed 10 times faster than with conventional models.
Disassembly before cleaning is no longer necessary. Scale is removed immediately by simply turning a handle without having to interrupt the steam flow. This only takes around 3 minutes per trap.
-
Reduces scale deposits
Complete redesign of all internal components.
・33 % higher bimetallic valve lift
・2.2 x higher spring opening force
・Enlarged valve seat, flow channel and cross-section
* Compared to previous Miyawaki products
-
Preventive measures to ensure the locking function
This product enables efficient, regular removal of scale. Regular removal prevents scale from impairing the closing function.
-
Outstanding durability
SCCV system (Self Closing and Centering Valve)/This is a mechanism developed by Miyawaki to increase valve service life.
Gentle closing increases the service life.
Remove the scale by simply turning a handle!
This temperature control trap has a mechanism that allows you to remove limescale deposits in the flow channel (of the valve hole) and empty it by simply turning a handle on the underside.
Typical applications
Suitable for steam tracing lines in systems.

*Can also be manufactured with a maximum operating pressure of 10 bar.
*It is possible to change the factory-set standard temperature. Please specify operating pressure and set temperature.
*Please refer to the installation instructions to find out how to adjust the set temperature.
●⊿t is the difference between the temperature of a temperature control trap when the valve is first opened and the condensate temperature
The temperature difference (⊿t) when the air initially flows through is large and indicates that the flow rate also increases.
* Curve1 shows the maximum capacity of the trap when discharging cold condensate.
**Curve2 shows the maximum capacity of the trap when discharging hot condensate at a temperature of 10 C (18 F) below the set temperature of the trap.
