Vacuum Breaker, Combination Air Valve IR-C70-C

BERMAD C70 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 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.

Product Features & Benefits
  • Sֺֺtraight flow body with higher than usual flow rates.
  • Aֺֺerodynamic full-body kinetic shield: Prevents premature
    closing without disturbing air intake or discharge.
  • Dֺֺynamic sealing: Prevents leakage under low pressure
    conditions (1.5 psi; 0.1 bar).
  • Mֺֺinimizes water spraying during air release: Innovative
    2-step function, automatic orifice (Patent Pending).
  • Tֺֺhree optional outlets (sideways, downwards, circular-surround
    mushroom configuration) that can swivel 360°:
  • Easy to install in a variety of site conditions.
  • Cֺֺompact, simple, robust and reliable structure with fully
    corrosion-resistant parts: Lower maintenance and increased
    life span.
  • Dֺֺesigned in compliance with functional standards
    and water service standards.
  • Fֺֺactory approval and Quality Control: Performance and
    specification tested and measured with specialized test
    bench, including vacuum pressure conditions.
Typical Product Applications
  • Pֺֺumping stations and deep well pumps: Air relief, surge
    protection and vacuum prevention.
  • Pֺֺipelines: Protection against air accumulation and vacuum
    formation at elevations, slope change points and at
    road / river crossings.
  • Wֺֺater networks: Protection against vacuum formation, surge
    and water hammers at points likely to experience water
