💨 NET® Air Valve ½” PA – Double Effect (Automatic + Kinetic Air Release Valve)

The NET® Air Valve ½” PA Double Effect is a compact dual-function air release valve designed to eliminate trapped air and admit air during vacuum conditions in pressurized pipelines, filtration systems, and circulation networks.
Its automatic and kinetic dual-action design ensures stable hydraulic performance, prevents air accumulation, and protects pipelines against pressure surges or vacuum collapse.

Constructed from reinforced polyamide (PA) with brass and P.P.S. internal components, this valve offers excellent mechanical strength, corrosion resistance, and long-lasting durability, even in chlorinated and chemically treated water.

✅ Key Features

• Double-effect operation:

  • Kinetic discharge – expels large air pockets during pipeline filling

  • Automatic air venting – releases small air bubbles during operation

• ½” BSP male threaded connection

• Reinforced PA (polyamide) body for strength and chemical resistance

• Brass and P.P.S. internal components – corrosion-resistant and precise

• Leak-proof float system for reliable operation under pressure

• Compact, lightweight, and easy to install

• Resistant to chlorine, UV exposure, and aggressive environments

• Designed for vertical installation
