COMBINATION AIR VALVE

C70-IP
Air Valves Series
Waterworks

BERMAD C70-IP 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 does not enalbe air intake in the event
of network draining.
With its advanced aerodynamic design, double orifice and inflow
prevention device, this valve provides excellent protection against
air accumulation with improved sealing in low pressure conditions.
The valve minimizes water spraying during air release.

C70-IP

  • 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.

  • Approved to AS4945-2017 / AS4020 & appraised with WSAA.

  • 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.
  • Pipelines: Protection against air accumulation at elevations, slope change points and at road/ river crossings.
