• Straight flow body with large diameter automatic orifice:
    Higher than usual air flow for PN16 & PN25
  • Aerodynamic, full-body kinetic shield: Prevents premature
    closing without disturbing air intake or discharge.
  • Dynamic Sealing: Prevents leakage under low pressure
    conditions (0.8 psi; 0.05 bar).
  • Elongated body design: Prevents solids from making contact
    with valve’s operating parts.
  • Compact, simple and reliable structure with fully corrosion-resistant
    internal parts: Lower maintenance and increased life span.
  • Two service ports: Enabling back flushing and drainage.
  • Threaded Side outlet (3″; DN80) for connection of Surge
    Protection (SP) or Inflow prevention (IP) devices.
  • Approved to AS4883-2017 & WSAA appraised.


BERMAD C80 is a high quality triple function combination air valve for a variety of sewage and wastewater networks and operating conditions. It evacuates air during pipeline filling, allows efficient release of air and gas pockets from pressurized pipes, and enables the intake of large volumes of air in the event of network draining. The elongated – body and lower float – is designed to reduce the contact between the fluid and the upper mechanism. With its advanced aerodynamic design, double orifice and Surge Protection device (optional), this valve provides excellent protection against air and gas accumulation and vacuum formation with improved sealing under low pressure conditions.   Available in PN16 & PN25  approved to AS4883-2017 and appraised to WSAA.
