Combination Air Valve for Sewage & Wastewater
Ductile Iron
BERMAD C80 is a high quality 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.
C80 is designed to facilitate longer periods of operation without maintenance and it is easy to maintain.

- Straight flow body: Higher than usual flow rates.
- 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.
- Two service ports: Upper and lower 1"; DN20 BSPT or NPT, enabling back flushing and drainage.
- Threaded Side outlet (3"; DN80) for connection of Surge Protection (SP) or Inflow prevention (IP) devices.
- Compact, simple and robust structure with fully corrosion resistant internal parts: Lower maintenance and increased life span.
- Certified to functional standards: SAI AS4883 (Australia).
- Factory approval and Quality Control: Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions.
Typical Applications
- Pumping stations: Air relief and vacuum prevention.
- Non clean water pipelines: Protection against air and gas accumulation and vacuum formation at elevations, slope change points and at road/river crossings.
- Wastewater treatment plants: Air relief, protection against air and gas accumulation and vacuum formation.
