The Cast Iron Priority Zoning Circulator delivers reliable flow control for multi‑zone hydronic heating systems, ensuring each zone receives the right amount of heat when needed. The 006‑ZF4‑1 model integrates a durable cast‑iron body with a 1/40 HP motor to provide consistent performance in residential and light‑commercial applications.
It utilizes a priority‑zone valve design that routes water through the primary zone first, then automatically supplies secondary zones once the primary demand is met, maximizing efficiency and reducing pump cycling.
Key System Performance Baselines:
- Flow Capacity: Up to 30 GPM at 30 ft head.
- Operating Pressure: Designed for 0‑200 psi system pressure.
- Energy Efficiency: Low‑wattage motor reduces electricity use.
- Durability: Cast‑iron construction resists corrosion and wear.
- Installation Flexibility: Threaded 1‑inch inlet/outlet for easy retrofit.
⚠️ Application Profile: Ideal for residential boiler zones, add‑on heat‑pump loops, small commercial steam‑less heating, and retrofit projects requiring reliable zone sequencing.
