Bermad - C-10 Vacuum Breaker Combination Air Valve
- Straight flow body with large diameter automatic orifice for higher than usual flow rates
- Aerodynamic full-body kinetic shield prevents premature closing without disturbing air intake or discharge
- Dynamic sealing prevents leakage under low pressure conditions (1.5 psi; 0.1 bar)
BERMAD C10 Air Valve
The BERMAD C10 is a high-quality combination air valve for a variety of irrigation networks and operating conditions. It evacuates air during pipeline filling, allows efficient release of air pockets from pressurized pipes, and enables large volume air intake in the event of network draining. With its advanced aerodynamic design, double orifice, and optional Surge Protection device, this valve provides excellent protection against air accumulation and vacuum formation, with improved sealing in low-pressure conditions. Specifically designed for irrigation applications.
Air Valve Series Features & Benefits
- Straight flow body with large diameter automatic orifice: Higher than usual flow rates.
- Aerodynamic full-body kinetic shield: Prevents premature closing without disturbing air intake or discharge.
- Dynamic sealing: Prevents leakage under low-pressure conditions (1.5 psi; 0.1 bar).
- Compact, simple and reliable structure: Parts are fully corrosion, chemical, and fertilizer resistant for lower maintenance and increased lifespan.
- Design in compliance with functional standards: Factory approval and Quality Control. Performance and specification tested and measured with a specialized test bench, including vacuum pressure conditions.
- Field-proven design: Suitable for use in irrigation applications with water quality such as river water, channel water, dam water, or treated effluent with high reliability.
Additional Features & Accessories
- Surge Protection (code SP) device: Smoother operation, preventing damage to the valve and the system.
- Inflow Prevention (code IP) device: Prevents intake of atmospheric air in cases where this could lead to damaged pumps, required re-priming, or disruption of siphons.
- Assisted Closing: The kinetic orifice is set to be partially closed (code AC) for controlled slow air relief, subsequently avoiding the possibility of a surge event during pipeline filling or column separation.
- Service Ports fitted: 1/8”; DN3 or 1/4”; DN6 plug (code P) for pressure gauge connection, check point, or test drain for air valve function.
- 90 degrees elbow: Snapped to the outlet, only for inlet sizes 3/4-1”; DN20-25.
- Addition of Female Thread 3/4” ”; DN20 (code 077, 017) to the outlet, only for inlet sizes ¾-1”; DN20-25.
- Extension with downwards outlet, only for inlet sizes 2-3”; DN50-80.
