Armstrong International D25934 Trap

The Armstrong International D25934 Trap, also known as the TS-3-3/4-ANGLE, is a high-performance angle pattern thermostatic radiator trap designed for demanding low-pressure steam heating systems. Featuring a rugged bronze body and a 3/4" connection, this industrial steam trap is engineered to handle pressures up to 65 PSI. It utilizes a precision-balanced thermostatic element that effectively discharges air and non-condensable gases while ensuring maximum condensate drainage for optimized steam system efficiency. The heavy-duty bronze radiator trap construction resists corrosion and provides reliable performance in schools, hospitals, and commercial buildings. By replacing failing units with the Armstrong TS-3 series, facilities can eliminate radiator hammering and significantly improve heat distribution. This replacement radiator trap is the preferred choice for HVAC professionals seeking a durable, drop-in solution for steam heating maintenance that meets strict manufacturer specifications for 3/4 inch angle configurations.

• Optimized Steam Efficiency: Rapidly removes air to allow steam to fill the radiator quickly.
• Industrial-Grade Durability: The heavy-duty bronze body ensures long-lasting operation in corrosive environments.
• High Pressure Rating: Safely operates in systems up to 65 PSI, exceeding standard low-pressure requirements.
• Simple Installation: The 3/4" angle pattern design allows for direct replacement of older TS-3-3/4-ANGLE models.
• Precision Operation: The sensitive thermostatic element prevents live steam loss while maximizing heat output.

How do I know if my TS-3 radiator trap has failed?
Common signs of a failed thermostatic steam trap include cold radiators, excessive hammering, or steam escaping into the return lines, which increases energy costs.

Is the Armstrong D25934 compatible with other brands?
While the Armstrong International D25934 Trap is a standard 3/4" angle pattern, you should verify center-to-face dimensions to ensure a seamless fit during steam system repair.

What is the maximum operating temperature for this bronze radiator trap?
The TS-3 series is designed for saturated steam environments typical of 65 PSI systems, maintaining structural integrity at temperatures exceeding 300°F.
