NON CLEAN, SEWAGE & WASTEWATER COMBINATION AIR VALVE WW C80
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 with large diameter automatic orifice:
Higher than usual air flow.
- 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.
- Factory approval and Quality Control: Performance and
specification tested and measured with specialized test
bench, including vacuum pressure conditions
- 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 road / river crossings.
- Wastewater Treatment plants: Air relief, protection against
air and gas accumulation and vacuum formation.
