Honeywell 126590 Adjustable Bleed Valve Assembly

The Honeywell 126590 Adjustable Bleed Valve Assembly is a compact (weighing around 0.05lbs) valve designed for precise control of fluid flow in HVAC systems, typically hydronic heating. Made of chrome-plated brass for durability, it features a 1/8 inch inlet for connecting to smaller pipes and a 1/4 inch outlet. While listed specifications include voltage (24V) and frequency (60Hz), these are not directly applicable to this particular valve. It operates mechanically, not electrically. By adjusting a screw, you can regulate the amount of fluid that bypasses the main flow path. This allows for tasks like purging air pockets or balancing pressure within the system, ensuring optimal performance of your hydronic heater.
