Designed to provide reliable water flow control and rapid system charging in commercial hydronic loops, the dual‑unit valve ensures efficient operation during heating and cooling cycles. The 110198LF model incorporates a fast‑fill feature that quickly restores system pressure after purging or maintenance.
The valve combines a three‑way throttling function with an integrated fast‑fill pilot, allowing pressure to be built up through a dedicated fill port while the main valve remains sealed. This dual‑action design minimizes water hammer and shortens start‑up times, delivering consistent flow rates and protecting equipment downstream.
Key System Performance Baselines:
- Fast Fill Capability: Restores pressure up to 150 psi within seconds.
- Three‑Way Control: Provides precise modulation for heating and cooling circuits.
- Reduced Water Hammer: Integrated pilot design mitigates pressure spikes.
- Durable Construction: Cast‑iron body resists corrosion in aggressive water chemistries.
⚠️ Application Profile: Ideal for commercial HVAC chillers, boiler feedwater systems, and large‑capacity hydronic heating loops where rapid system recovery and precise flow control are critical.
