Automatic Air Vent Valve 1/2" - Nickel Plated Brass - ISO 228

Automatic Air Vent Valve – Eliminate Air Pockets & Optimize System Performance

Designed for heating and air conditioning systems, this automatic air vent valve continuously removes accumulated air without manual intervention, protecting your system from corrosion, cavitation, and performance loss.

Key Benefits

• Prevents Galvanic Corrosion: Eliminates excess oxygen that causes pipe degradation
• Stops Cavitation: Protects pumps and components from damaging air bubbles
• Maximizes Heating/Cooling Efficiency: Removes air pockets from radiators and fan-coil units for optimal heat transfer
• Automatic Operation: No manual venting required – works continuously under system pressure
• Optimized Flow Rate: Air discharge increases with system pressure up to 6 bar maximum

Installation Guidelines

Install vertically at the highest points of your system, including distribution manifolds, riser pipes, and wherever air pockets typically form. For normal operation, leave the cap loose to allow automatic venting.

Technical Specifications
