The Air & Vacuum Valve discharges air at high flow rates during the filling of the system and admits air at high flow rates during drainage , pump shut-off or at water column separation.
Agricultural and landscape irrigation laterals.
The air & vacuum valve discharges air at high flow rates during the filling of the system and admits air at high flow rates during drainage, pump shut-off or at water column separation.
High velocity air will not blow the float shut. Water entry will lift the float which seals the valve.
The smooth discharge of air reduces pressure surges and other destructive phenomena.
At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system. The intake of air in response to negative pressure protects the system
from destructive vacuum conditions and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.
As the system starts to fill, the valve functions according to the
1. Entrapped air is released by the valve.
2. Water enters the valve, lifting the float and sealing the valve.
When internal pressure falls below atmospheric pressure
The float will immediately drop down, opening the air & vacuum orifice. Air will enter the system.
1. Working pressure range: 0.2 - 16 bar
2. Testing pressure: 18 bar
3. Working Temperature : 60ºC
4. Maximum intermittent temperature : 90ºC
