Designed to safely remove condensate and excess water from hydronic and HVAC loops, this free‑floating lever drain trap provides dependable operation under high pressure. The 1-LD model fits seamlessly into standard pipework, offering a 5/64″ orifice and a 300 psig rating.
The trap features a cast‑iron body with a floating lever that automatically seals when water is absent, preventing air ingress. When the lever is lifted, condensate flows freely through the precisely sized orifice, allowing quick draining without tools.
Key System Performance Baselines:
- Maximum Working Pressure: Handles up to 300 psig, ensuring durability in high‑pressure applications.
- Orifice Size: 5/64″ aperture delivers accurate flow control for condensate removal.
- Lever Action: Free‑floating lever enables rapid, tool‑free draining and automatic reseating.
- Construction: Cast‑iron body resists corrosion and mechanical wear.
⚠️ Application Profile: Ideal for boiler condensate lines, chilled‑water system drains, fire‑sprinkler condensate loops, and any high‑pressure HVAC or hydronic circuit requiring reliable condensate removal.
