The A.R.I. AV 10 is a plastic kinetic air and vacuum valve that can admit or
discharge large quantities of air to/from a system. The air and vacuum valves are used predominantly where the installation is regularly drained and filled to prevent implosion (due to vacuum) and water hammer (due to water columns ‘springing back’). Good venting allows the system to be filled faster and more safely.
Underground drip irrigation installations in, for example, garden or landscape irrigation for the discharge of relatively large quantities of air
