Miyawaki TBH81 Temperature Control Steam Trap
Manufacturer: MIYAWAKI Inc.
Model: TBH81
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.
Suitable for high pressure, high temperature ranges and superheated steam
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.
Quick startup
Swiftly discharges the initial cold condensate and air.
Energy saving effect
A significant energy saving effect is achieved by controlling the temperature of discharged condensate.
With low operating noise and very little flash steam
Typical applications
Suitable for ultra-high pressure and high temperature uses such as superheated lines, turbine headers, and other such applications.

*Available flange standards: ASME/JPI 1500lb, 2500lb, DIN PN100, 160
*Socket weld standards: ASME 2500lb, JPI 2500lb, JIS sch 160
Maximum allowable pressure (PMA): 25,0MPa (3625psig) (at 492℃ (918℉))
Maximum allowable temperature (TMA): 593℃ (1100℉) (at 3,7MPa (536psig))
Minimum operating differential pressure (⊿PMN): 2.0MPa (290psig) ⊿PMN is the minimum operating differential pressure between the trap inlet and outlet.
In the absence of any particular instructions for the set temperature, the product is adjusted to the standard factory set temperature above for shipment.
Please use a set temperature that is at least 30℃ (86℉) lower than the saturation temperature for the steam pressure in use.
*The body of the TBH81 can also be manufactured using chromium molybdenum forged alloy steel product A182 F22.
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.
