Miyawaki TB9BN-C Temperature Control Steam Trap
Manufacturer: MIYAWAKI Inc.
Model: TB9BN-C
Features
Complete steam containment
The temperature control trap operates with an adjustable subcooling of condensate. Thus maintaining a certain condensate level in the trap. This mechanism provides a 100% tight sealing and effectively prevents steam loss during operation.
Superb durability
The MIYAWAKI SCCV (Self Closing and Centering Valve) System has the effect of increasing durability by achieving soft closing during operation.
Consisting of a free rotating valve that is centered and guided by the condensate flow, hence perfectly fitted in the valve seat even under extreme conditions of high pressure applications. This significantly reduces wear and erosion of the valve components.
Energy saving effect
A significant energy saving effect is achieved by controlling the temperature of discharged condensate. Especially in application where sensible heat of condensate can be used for heating purpose, this trap reduces steam consumption significantly.
Blowdown valve
A blowdown valve to eliminate dirt from pipes and scale that has entered and built up in the trap without having to disassemble the trap.
TB9BN-C up to 0,98MPa (142psig)
Typical applications
Suitable for steam main lines, steam tracing, tank heating, heaters, and other such uses.

Maximum allowable pressure (PMA): 0,98MPa (142psig) PMA is the pressure that can be tolerated by pressure-resistant parts (body).
Maximum allowable temperature (TMA): 183℃ (361℉) TMA is the temperature that can be tolerated by pressure-resistant parts (body).
Minimum operating differential pressure (⊿PMN): 0,01MPa (1.5psig) ⊿PMN is the minimum operating differential pressure between the trap inlet and outlet.
*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.
