Product Q&A

Q:How to select the right air release valve for water pipeline systems?

For municipal, industrial pipelines, and pump stations, Double Orifice Air Release Valves are ideal. Consider pipeline diameter, pressure (PN10/PN16), and air accumulation. High-capacity valves ensure efficient air removal and stability in long pipelines.

Q:Why are air release valves crucial in water and fire protection systems?

They expel trapped air pockets, enhancing flow efficiency, preventing water hammer. In fire and municipal systems, they maintain capacity, prevent surges, protect pumps and pipelines, ensuring reliability and safety.

Q:Are air release valves suitable for high-frequency operation and variable flow conditions?

Modern automatic air release valves feature sensitive floats and robust seals that react swiftly to flow changes. Quality combination air valves withstand frequent cycles and pressure shifts, ensuring top sealing and longevity.

Q:How do air release valves boost efficiency in HVAC and chilled water systems?

Air release valves remove air in chilled and hot water systems, preventing air locks that impede heat transfer. They enhance flow, remove air pockets, boost system performance, save energy, and protect equipment from corrosion and cavitation.

Q:What materials are used for the valve body and internal components?

The valve features a CF8 stainless steel body and cover, SS304 filter screen, and NBR gasket for durability and corrosion resistance.
