Steam Traps with Two-Bolt Connection
Steam Traps with Two-Bolt Connection DC1-21U
TBU7-U
Features/Applications
Features
Quick and Easy Replacement
Universal connection allows removal with just two bolts, minimizing maintenance time and production downtime.
Adjustable Temperature After Installation
Temperature can be adjusted on-site to match operating conditions, preventing overheating and ensuring stable performance.
Flexible Integration for Efficient and Simplified Piping
Compatible with CTC-P and UNC for standard pipeline and manifold configurations, enabling efficient steam distribution and a simplified piping layout.
Durable and Reliable Construction
Stainless steel (A182 F316) body offers excellent corrosion resistance and long service life, even in harsh environments.
Typical applications
Suitable for steam main lines, trace lines, and other such applications.

●Maximum allowable pressure (PMA): 5,0MPa (725psig) PMA is the pressure that can be tolerated by pressure-resistant parts (body).
●Maximum allowable temperature (TMA): 400℃ (752℉) 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

● Δt value is the difference of temperature between the real temperature of the discharging condensate and the adjusted temperature of the trap. The temperature difference (⊿t) upon the initial passage of air is great, and indicates that the flow rate will also increase.
● The condensate flow rate listed in this table is the value when the product is set to 100℃ and discharging condensate at 90℃.
* The "Cold Water" curve shows the trap's maximum capacity when discharaging cold condensate.
* The Δt=10℃ curve shows the trap's maximum capacity when discharging hot condensate at a temperature of 10°C (18°F) below the adjusted temperature of the trap.
