Threaded air release valve

Threaded automatic air vent. Direct installation via threaded connection. It automatically releases accumulated air in pipelines to resolve air blockage and noise issues. Equipped with negative pressure air intake protection function, the valve body features stable sealing and good corrosion resistance. Widely used in heating, water supply and central air conditioning circulation pipelines. Easy to install and requires no manual operation during daily use.

Detail

Parameters

Threaded automatic air vent adopts threaded connection for easy installation without welding. It relies on a float mechanism to automatically discharge accumulated air inside the pipeline, eliminating air blockage, reducing water flow noise and improving water circulation efficiency. When negative pressure occurs after pump shutdown, the valve can intake air automatically to protect the pipeline from negative

pressure damage. The valve body delivers reliable sealing and is available in brass, stainless steel and ductile iron options, featuring good corrosion resistance and leak-proof performance. Suitable for underfloor heating, radiators, central air conditioning, tap water and various circulating water pipelines. It

operates automatically once installed at the high point of the pipeline for hassle-free maintenance.

1. Easy & Fast Threaded Installation

Comes with standard thread interface, direct screwin in stallation without welding. Saves construction time and fits narrow pipeline

spaces perfectly.

2. Automatic Air Release & Smooth Water Circulation

Built-in float structure automatically exhausts trapped air inside pipelines. Effectively eliminates air blockage, reduces water

flow noise and improves overall circulation efficiency.

3. Negative Pressure Protection Function

Automatically intakes air when the system produces negative pressure after pump shutdown, preventing pipeline deformation and

damage.

4. Excellent Sealing & Corrosion Resistance

Adopts high-quality brass, stainless steel or ductile iron materials. Stable sealing performance, no water leakage, long service life and

strong anti-corrosion ability.

5. Maintenance-Free & Wide Application

Fully automatic operation without manual control. Ideal for heating systems, radiators, floor heating, central air conditioning and water

supply circulating pipelines.
