Armstrong International D23324 Radiator Trap

The Armstrong International D23324, also identified as the TS-2-1/2-ANGLE, is a heavy-duty 1/2 inch angle pattern radiator trap engineered for reliable condensate drainage in low-pressure steam heating systems. Constructed with a durable bronze body, this thermostatic trap is rated for operational pressures up to 50 PSI. It features a balanced pressure phosphor bronze bellows caged in stainless steel, ensuring precise response to temperature changes while resisting water hammer and corrosion. This steam radiator trap replacement is specifically designed for commercial steam heating applications, providing an airtight seal against steam while efficiently venting air and non-condensable gases. Field technicians prefer this model for its renewable thermostatic element and seat, allowing for straightforward maintenance without breaking pipe connections. Whether you are performing a radiator trap repair or a new installation, the D23324 provides the robust performance required for two-pipe steam systems.

• High-Grade Construction: The bronze body radiator trap ensures long-term resistance to pitting and thermal stress.
• Interchangeable Design: Fully compatible with systems requiring the TS-2 angle pattern configuration for easy retrofit.
• Effective Air Venting: Specialized bellows design prevents air binding, optimizing heat transfer across the radiation surface.
• Pressure Versatility: Capable of handling fluctuating loads in systems rated up to 50 PSI steam pressure.

Common Questions

How do I verify if the D23324 is the correct fit for my existing piping?
The D23324 features a standard 1/2" NPT inlet and outlet in an angle pattern. If your current setup is a TS-2-1/2-ANGLE, this unit is a direct physical and functional match.

Can this trap be serviced without removing the body from the radiator?
Yes, the internal thermostatic cage and seat are accessible from the cap, allowing for rapid internal component replacement while the body remains in the piping run.

What causes these traps to fail open, and how does the D23324 address this?
Traps typically fail due to scale buildup or bellows fatigue. The Armstrong TS-2 utilizes a shielded stainless steel cage to protect the bellows from abrasive debris, extending the service life between maintenance intervals.
