Designed to safely remove condensate and excess water from boiler and hydronic systems, this free‑floating lever drain trap ensures reliable pressure relief and maintenance of system efficiency. The 1-LD model from Armstrong features a 1/8" orifice capable of handling up to 121 psig, making it ideal for high‑pressure applications.
The lever‑activated float rises with water level, opening the orifice to vent pressure once the preset threshold is reached. When the water drains below the set point, the float drops, closing the valve to prevent backflow and maintain system integrity.
Key System Performance Baselines:
- Pressure Rating: Handles up to 121 psig, suitable for most commercial boiler loops.
- Orifice Size: 1/8" inlet ensures precise flow control and minimizes water hammer.
- Float Design: Free‑floating lever provides quick response to changing water levels.
- Installation Flexibility: Compatible with standard 1/8" pipe threads for easy retrofit.
⚠️ Application Profile: Boiler condensate lines, hydronic heating loops, fire‑tube boiler systems, and high‑pressure steam condensate return.
