Bermad Combination Air and Vacuum Release Valve
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.
Typical Applications
- Main Irrigation Networks – Air relief, protection against air accumulation and vacuum formation downstream of pumps, along supply lines and at elevations in main irrigation networks.
- Irrigation Control Heads – Air relief, 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
Features
- Fully approved AS4956-2017 / AS4020 / WSAA rated to PN12
- Optional inflow protection (IP) & surge protection (SP)
- 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
Additional Features
- Surge Protection (anti-slam) – Smoother operation, preventing damage to the valve and the system (C10-SP).
- Inflow prevention – Prevents intake of atmospheric air in cases where this could lead to damaged pumps, required re-priming, or disruption of siphons (C10-IP)
