Air Release Valve - AQ88P 25mm product_screen cartridge 14 49 57 2Automat AQ air release valves automatically vent trapped air from irrigation mains at system start up and admit air during system shutdown to prevent vacuum lock and pipe collapse. Trapped air in irrigation pipework causes pressure fluctuations, uneven sprinkler performance and accelerated water hammer damage; correct air valve installation at high points and ends of mains eliminates these issues. Available in standard and continuous vacuum service
