Description
Overview
The Armstrong International 125A6 is a Series A Cast Iron Float & Thermostatic (F&T) Steam Trap engineered for reliable, continuous condensate discharge in a wide range of steam heating and process applications. With a robust cast iron body, a standard 1-1/2″ NPT connection, and a maximum working pressure of 125 PSI, this trap delivers the durability and performance that commercial and industrial steam systems demand.
Key Features
- Series A cast iron body construction for long-lasting durability in demanding steam environments
- 1-1/2″ NPT standard connection for straightforward installation into existing piping
- 125 PSI maximum working pressure rating
- 7/32″ orifice for precise, efficient condensate flow control
- Integrated thermostatic air vent automatically purges air and non-condensable gases on startup and during operation
- Float & thermostatic design provides continuous, modulating condensate discharge — no slugging or water hammer
How It Works
The float mechanism responds continuously to condensate levels, opening the valve to discharge condensate as it accumulates. The built-in thermostatic air vent opens at startup to rapidly vent air and non-condensables, then closes as steam temperature is reached — maximizing system efficiency and reducing warm-up times.
Typical Applications
- Steam heating mains and branch drip legs
- Unit heaters and heat exchangers
- Steam coils and radiators
- Industrial process steam equipment
- Commercial boiler systems
