💨 NET® Air Valve 3” PA – Triple Effect (Automatic + Kinetic + Vacuum Air Release Valve)

The NET® Air Valve 3” PA Triple Effect is a high-capacity triple-function air valve designed to manage air in large pressurized water systems, including swimming pool filtration, irrigation, and industrial pipelines.
It performs three essential functions: automatic air release, kinetic discharge, and vacuum relief, ensuring maximum protection against pressure surges, vacuum formation, and trapped air pockets.

Manufactured from reinforced polyamide (PA), the valve offers exceptional mechanical strength, corrosion resistance, and long service life even under harsh environmental and chemical conditions.
It is ideal for large-diameter pipelines and installations requiring high air flow performance.

✅ Key Features

• Triple-effect functionality:

  • Kinetic discharge for large air release during filling

  • Automatic air venting of small trapped air bubbles during operation

  • Vacuum relief during draining or negative pressure conditions
