OPERATION
- Expells air from the pipe network as the lines fill. When the water reaches the interior of the valve the float rises and seals the discharge outlet.
- Continually expels air automatically when residual pockets of air reach the valve. Air pockets are expelled regardless of water pressure.
- Prevents vacuum and subsequent pipe collapse because as soon as pressure is decreased the float drops, opening the seal and allowing outside air into the pipe system.
SPECIFICATIONS
- 50mm (2") Male BSP inlet.
- Seals at 20 kPa water pressure.
- 1600 kPa maximum working pressure.
- Air volume extracted at 30 kPa is 370 m³/hr.
- Fibreglass reinforced Polyamide body and base for UV protection.
