Advantages
-
1 Simple Structure and Low Failure RateThere is only floating ball + sealing nozzle inside, without complex mechanism.
It is not easy to jam and block, and the clean water system is basically maintenance free. -
2 Wide Application Scope and Strong UniversalityMunicipal water supply, fire protection, heating and ventilation, irrigation and industrial circulating water can be used.
The caliber is complete, and the common specifications of DN25~DN100 are complete.
Easy installation and maintenance. -
3 Vertical InstallationDuring maintenance, only the front valve needs to be closed, and the whole pipeline does not need to be disassembled.
-
4 Cost-EffectiveIt is cheaper than the compound exhaust valve and more durable than the small caliber screw valve.
Low cost for long-term use, suitable for batch use in projects.
Packing

Standard export wooden case packaging
Frequently Asked Questions
-
Q What is a single port air exhaust valve and how does it work?A single port air exhaust valve is a fully automatic device used to release trapped air from pipelines. It operates via a floating ball mechanism — when air accumulates, the ball drops, opening the port to release the air; when water rises, the ball floats up and seals the port automatically, requiring no manual intervention.
-
Q What materials and standards does this air exhaust valve comply with?This single port air exhaust valve is made from ductile iron and manufactured using investment casting. It complies with multiple international standards including BS, API, DIN, and JIS, making it suitable for a wide range of global applications.
-
Q What is the operating temperature range of this valve?The single port air exhaust valve is designed for operating temperatures between -20°C and 120°C, making it suitable for a wide variety of environments including cold climates and moderate-heat industrial applications.
-
Q What pipeline systems is this air exhaust valve suitable for?This valve is highly versatile and suitable for municipal water supply systems, fire protection pipelines, heating and ventilation systems, agricultural irrigation networks, and industrial circulating water systems. Available sizes range from DN25 to DN100.
-
Q How is the single port air exhaust valve installed and maintained?The valve is installed vertically on the pipeline. Maintenance is simple — only the front valve needs to be closed during servicing, so the entire pipeline does not need to be dismantled. Its straightforward internal structure means it is virtually maintenance-free in clean water systems.
-
Q How is the product packaged for export?All single port air exhaust valves are packaged in standard export wooden cases, ensuring safe and secure transportation for international shipments. This packaging method meets common export requirements and protects the product during transit.
