Bermad IR-C10-P-AU Combination High Quality Air Valve (PN10)

Bermad C10 is a high-quality combination air valve designed for a variety of applications such as Irrigation Water, Sea Water, Treated Effluent & Drinking Water applications. It evacuates air during pipeline filling, allows the efficient release of air pockets from pressurised pipes, and enables large volume air intake in the event of network draining.  With its advanced aerodynamic design and double orifice, this valve provides excellent protection against air accumulation and vacuum formation, with improved sealing in low-pressure conditions.  Options that can be added to the 50mm valve are Surge protection, Assisted closure or Inflow protection kits.

FEATURES

• Fully approved AS4956-2017 / AS4020 / WSAA rated to PN12
• Optional inflow protection (IP) , surge protection (SP) or Assisted closure (AC)
• Low pressure sealing on all PN12 valves to 10Kpa
• Extremely high air flow capacity for use on larger diameter pipelines
• Fitted with lower body plug for gauge, check point or drain valves.

MATERIALS

• Body: Glass-reinforced Nylon
• Float Assembly: Polypropylene, Glass Reinforced Nylon.
• Elastomers: EPDM, Optional - Viton

OPERATIONAL DATA

APPLICATIONS

• Main Irrigation Networks: Protection against air accumulation and vacuum formation downstream of pumps, along supply lines and at elevations in main irrigation networks.
• Irrigation Control Heads: Protection against air accumulation and vacuum formation at filtration and fertilization stations and downstream of main control valves.
• Infield Systems: Protection against air accumulation and vacuum formation in proximity to water meters and automatic regulators.
• Landscape Irrigation: Protection against air accumulation and vacuum formation.
• Pumping stations: Maximising pumping efficiency, priming capabilities and reducing the possibility of pressure surges during power failure modes.
