Product Q&A
Q:How to select the right air release valve for water pipeline systems?
A:
For municipal supply, industrial pipelines, and pump stations, Combination Air Release Valves (Double Orifice) are recommended. Consider diameter, pressure (PN10/PN16), and air conditions. High-capacity valves suit long pipelines and high points for efficient air removal and stability.
Q:Why are air release valves vital in water supply and fire protection systems?
A:
They remove trapped air, improving flow efficiency and preventing water hammer. In fire protection and municipal systems, they maintain capacity, prevent surges, and protect equipment, ensuring reliability and safety.
Q:Suitable for high-frequency operation and variable flow conditions?
A:
Yes. Modern automatic air release valves use responsive float mechanisms and durable sealing to adapt quickly to flow changes. High-quality combination air valves manage frequent cycles and pressure variations while ensuring excellent sealing and longevity.
Q:How do air release valves improve efficiency in HVAC and chilled water systems?
A:
Air release valves remove accumulated air in chilled and hot water systems, preventing air locks that hinder heat transfer. By optimizing flow and eliminating air pockets, they enhance performance, cut energy use, and protect equipment from corrosion and cavitation.
