BERMAD C30 Combination Air Valve

The BERMAD C30 is a high-quality combination air valve suitable for various water 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 prevents vacuum formation, with improved sealing in low-pressure conditions.

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).
• The boss on the base can be tapped with a thread for pressure gauge connection, check point, or test drain for air valve function.
• Threaded Side outlet (2”; DN50) for connection of Surge Protection (code SP) or Inflow prevention (code IP) devices.
• Compact, simple, and reliable structure with fully corrosion-resistant internal parts; lower maintenance and increased lifespan.
• Design in compliance with functional standard and water service standards.
• Factory approval and Quality Control: Performance and specification tested and measured with a specialized test bench, including vacuum pressure conditions.

Additional Features & Accessories

• Air Valve Series C30-P C30-C
• 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 ¼”;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 ¾-1"; DN20-25.
• Addition of Female Thread ¾”; 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.

Typical Applications

• Pipelines: Protection against air accumulation and vacuum formation at elevations, slope change points, and road/river crossings.
• Water networks: Protection against air accumulation and vacuum formation.
• In proximity to control valves and water meters: Prevention of inaccurate pressure regulation and biased readings due to air existence in these devices.
