Description
NDS air/vacuum valve for controlling aeration and ventilation in drip lines
The ABS valve is an important component of a drip irrigation system. It should be used primarily in underground systems in conjunction with valve shafts at the highest point in the drip line.
The valve has a dual function:
- It vents your system at startup.
- It prevents a vacuum from forming in the system when it is switched off.
- Allows trapped air to escape to prevent water hammers
- Removes trapped air to eliminate blockages
- Prevents cavitation caused by imploding air bubbles
