Miyawaki TBU4-SR Temperature Control Steam Trap
Manufacturer: MIYAWAKI Inc.
Model: TBU4-SR
Features
Takes only 1/10th of the previous time required to remove scale
Disassembly before cleaning is no longer needed. Remove scale instantly by simply turning a handle with no need to stop the flow of steam. The time required is approximately 3 minutes per trap.
Reduces scale buildup
Complete redesign of all internal unit components.
・33% increase in bimetal valve stroke volume
・Spring opening force 2.2 times stronger
・Enlarged valve seat flow channel and space
*Compared with previous Miyawaki products
Pre-emptive action before closing performance deteriorates
This product enables efficient regular scale removal work. Poor closing performance caused by scale can be prevented through regular scale removal.
Superb durability
SCCV (Self Closing and Centering Valve) System / This is an original mechanism developed by Miyawaki to increase valve durability.
It has the effect of increasing durability by achieving soft closing.
Remove scale by simply turning a handle!
This temperature control trap has a mechanism that allows you to remove scale that has built up in the flow channel (of the valve hole) and discharge it by simply turning a handle at the bottom.

*Can also be manufactured with a maximum operating pressure of 1,0MPa (145psig).
*It is possible to change the standard factory set temperature. Please specify the operating pressure and set temperature.
*Please refer to the installation manual how to adjust the set temperature.
Discharge Capacity
●⊿t is the difference between the temperature of a temperature control trap when the valve is initially opened and condensate temperature.
The temperature difference (⊿t) upon the initial passage of air is great, and indicates that the flow rate will also increase.
* Curve1 shows the trap’s maximum capacity when discharaging cold condensate.
**Curve2 shows the trap’s maximum capacity when discharaging hot condensate at a temperature of 10°C (18°F) below the adjusted temperature of the trap.
