COMBINATION AIR VALVE
C75-AC
Waterworks
BERMAD C75-AC is a high quality combination air valve for a
variety of water networks and operating conditions. It evacuates
air during pipeline filling, allows efficient release of air pockets
from pressurized pipes, and enables large volume air intake in
the event of network draining.
With its advanced aerodynamic design, double orifice and assisted
closing Surge Protection (Anti-slam / slow closing) device, this
valve provides excellent protection against air accumulation,
vacuum formation and pressure surges, with improved sealing
in low pressure conditions. The valve minimizes water spraying
during air release

-
- Straight flow body with nominal (equal) inlet and outlet size: Higher than usual flow rates.
- Aerodynamic full-body kinetic shield: Prevents premature closing without disturbing air intake or discharge.
- Dynamic sealing: Prevents leakage under low pressure conditions (1.5 psi; 0.1 bar).
- Minimizes water spraying during air release: Innovative 2-step function, automatic orifice (Patent Pending).
- Three optional outlets (sideways, downwards, circularsurround mushroom configuration) that can swivel 360°: Easy to install in a variety of site conditions.
- Compact, simple, robust and reliable structure with fully corrosion-resistant parts: Lower maintenance and increased life span.
- Factory approval and Quality Control: Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions.
Typical Applications
- Pumping stations and deep well pumps: Air relief, surge protection and vacuum prevention.
- Pipelines: Protection against air accumulation and vacuum formation at elevations, slope change points and at road/ river crossings.
- Water networks: Protection against vacuum formation, surge and water hammers at points likely to experience water column separation.
