Automatic Air Vent Valve Efficiently removes trapped air from hydronic heating systems to optimize performance and enhance heat distribution for consistent warmth throughout the space. Long Lasting Construction Solid brass material with a maximum working pressure of 10 bar and water temperature up to 110 C, providing reliable operation in demanding heating conditions. For Easy Installation Designed for vertical placement on boilers or points in heating systems with an external thread connection for straightforward setup and immediate air bleeding. Versatile Compatibility Suitable for various heating equipment including hot water radiators and small unit heaters with bidirectional operation and exhaust without drainage function. Use Scenarios Scenario 1: In a residential boiler system with radiators, install at a point to automatically vent trapped air, reducing cold spots and improving overall heat distribution. Scenario 2: Retrofit an older hydronic system suffering from air blockages; the valve provides automatic venting to minimize manual bleeding and maintain efficiency. Scenario 3: In a small unit heater or radiant floor heating installation where air pockets commonly form, the vent maintains efficient operation without draining water.
