Wholesale Combination Air Valve DN100 DN200 for Large Scale Pipeline Projects

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

Air release valves are essential for removing trapped air pockets that can reduce flow efficiency and cause water hammer. In fire protection and municipal water systems, they help maintain full pipeline capacity, prevent pressure surges, and protect pumps and pipelines from damage, ensuring reliable system performance and safety.

Yes. Modern automatic air release valves feature sensitive float mechanisms and robust sealing designs that respond quickly to changing flow conditions. High-quality combination air valves can handle frequent start-stop cycles and varying pressures while maintaining excellent sealing performance and long service life.

Air release valves effectively eliminate accumulated air in chilled and hot water circulation systems, preventing air locks that reduce heat transfer efficiency. By maintaining optimal flow and eliminating air pockets, they help improve system performance, reduce energy consumption, and protect equipment from corrosion and cavitation.

The product description does not specify a warranty period, but all valves undergo 100% inspection including visual and function checks before delivery.
