Characteristics

★

The single port air vent valve is fully automatic operation, requiring no manual intervention. It features low resistance, ensuring no impact on pipeline flow. Its simple design makes maintenance easy and prevents jamming.

Characteristics

Advantages

Simple structure and low failure rate: Only floating ball and sealing nozzle inside, no complex mechanisms. Not easy to jam or block; maintenance-free for clean water systems.
Wide application scope: Suitable for municipal water supply, fire protection, heating, ventilation, irrigation, and industrial circulating water. Complete caliber specifications from DN25 up to DN100.
Vertical installation: Easy maintenance; only the front valve needs to be closed, no need to disassemble the entire pipeline.
Cost-effective: More affordable than compound exhaust valves and more durable than small caliber screw valves. Ideal for batch use in large projects.
