Stainless Steel DN25 1 Inch Automatic Air Vent Valve for High Efficiency Systems

Product Description

The stainless steel DN25 automatic air vent valve is designed for demanding HVAC and water circulation systems where durability and corrosion resistance are critical. It provides continuous air elimination to maintain smooth system operation.

Operating Mechanism

Inside the valve, a float-controlled mechanism responds to air accumulation. When air enters, the valve opens automatically to release it. When water replaces the air, the valve closes tightly to prevent leakage.

Technical Highlights

• Size: DN25 / 1 inch connection

• Thread type: BSP / NPT available

• Material options: stainless steel / brass Hpb59-1

• Automatic float-type air discharge system

• Suitable for high-temperature water circulation

• Compact structure for tight installation spaces

Application Fields

• Industrial HVAC systems

• Floor heating distribution manifolds

• Boiler air release points

• Closed-loop water circulation systems

Final Note

The stainless steel DN25 air vent valve provides long-term stability and is ideal for systems requiring higher corrosion resistance and reliable automatic air removal.
