This DAV-P-KA has been designed for efficient discharge and intake of air in water transport systems, filtering systems, containers, and other places where confined air could impair the systems operation.
The valve is appropriate for:
- Expelling the air at high flow velocity during the initial filling of the systems
- Introducing large quantities of air when the pipe drains, maintaining atmospheric pressures in the pipe and preventing collapse and cavitation damage to the conduits
- Relieving the entrained air from the water, while the network is pressurize
FEATURES & ADVANTAGES
- The valve ensures a secure seal in any condition, including low system pressure, to prevent leaks.
- The float’s aerodynamic design promotes high-velocity airflow, ensuring it remains open until water reaches the valve.
- The threaded outlet elbow provides flexibility for different drain connection options.
- The valve’s simplified design consists of a minimal number of parts, making it easy to disassemble for maintenance purposes.
