Product Q&A

Q:How to choose the right air release valve for water pipelines?

For municipal water, industrial pipelines, and pump stations, Combination Air Release Valves (Double Orifice) are recommended. Consider pipeline diameter, operating pressure (PN10/PN16), and air accumulation. High-capacity automatic air vent valves suit long pipelines and high points for efficient air removal and stability.

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

They remove trapped air, enhancing flow efficiency, preventing water hammer. In fire protection and water systems, they maintain full capacity, prevent surges, and protect pumps and pipelines, ensuring performance and safety.

Q:Are air release valves suitable for frequent operation and variable flow?

Yes. Modern automatic air release valves have sensitive floats and robust seals that quickly respond to flow changes. High-quality combination air valves manage frequent start-stop cycles and varying pressures, ensuring excellent sealing and long service life.

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

Air release valves remove accumulated air in chilled and hot water systems, preventing air locks that hinder heat transfer. By ensuring optimal flow and eliminating air pockets, they enhance system performance, reduce energy use, and protect equipment from corrosion and cavitation.

Q:What materials are used for the internal components?

The internal components consist of a stainless steel float and a stainless steel stem, providing high corrosion resistance and durability.
