💨 ECO Air Valve ¾” NPT PA – Double Effect (Automatic + Kinetic Air Release Valve)

The ECO Air Valve ¾” NPT PA Double Effect is a dual-function automatic air valve designed to ensure efficient removal of trapped air and protection against vacuum conditions in pressurized water and filtration systems.
It integrates automatic and kinetic functions, maintaining optimal hydraulic performance and preventing air locks, pressure surges, and vacuum collapse in pipelines.

Built from reinforced polyamide (PA) with brass and P.P.S. internal components, this valve provides exceptional durability, chemical resistance, and long service life, even in chlorinated or chemically treated water environments.
The NPT male connection allows compatibility with North American standard piping systems.

✅ Key Features

• Double-effect operation:

  • Kinetic discharge – expels large air pockets during filling or startup

  • Automatic venting – releases small trapped air during operation

• ¾” NPT male connection (ANSI thread standard)

• Reinforced PA (polyamide) body – corrosion- and UV-resistant

• Brass and polymer internal components ensure high reliability

• Leak-proof float system for precise and maintenance-free performance

• Compact, lightweight construction for easy installation

• Designed for vertical mounting

• Suitable for high-pressure applications up to PN25
