💨 NET® Air Valve ¾” PP – Double Effect (Automatic + Kinetic Air Release Valve)

The NET® Air Valve ¾” PP Double Effect is a dual-function air release valve designed to automatically discharge trapped air and admit air during vacuum conditions in pressurized water systems, filtration circuits, and pipelines.
Manufactured from high-grade polypropylene (PP), it provides excellent chemical resistance, durability, and reliable operation under a wide range of pressures and environmental conditions.

This valve combines automatic and kinetic functions, ensuring smooth hydraulic performance, preventing air locks, and protecting pipelines against vacuum collapse.
It is ideal for pool filtration systems, irrigation networks, and water treatment installations.
