Frequently Asked Questions
QWhat 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.
QWhat materials and standards does this air exhaust valve comply with?
This valve is made from ductile iron using investment casting. It complies with international standards including BS, API, DIN, and JIS, making it suitable for global applications.
QWhat is the operating temperature range of this valve?
It is designed for operating temperatures between -20°C and 120°C, suitable for cold climates and moderate-heat industrial environments.
QWhat pipeline systems is this air exhaust valve suitable for?
The valve is versatile for municipal water, fire protection, HVAC, agricultural irrigation, and industrial circulating water systems. Sizes available: DN25 to DN100.
QHow is the single port air exhaust valve installed and maintained?
It is installed vertically. During maintenance, only the front valve needs closing, avoiding pipeline dismantling. Its simple internal structure is virtually maintenance-free in clean water systems.
QHow is the product packaged for export?
All valves are packaged in standard export wooden cases to ensure safe transportation for international shipments and meet export requirements.
