Product Description

Model C10

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 Surge Protection device (optional), this valve, this valve provides excellent protection against air accumulation and vacuum formation, with improved sealing in low pressure conditions.

Specifically designed for irrigation applications.

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 whose parts are fully corrosion, chemical and fertilizer resistant: Lower maintenance and increased life span.
• ֺDesign in compliance with functional standards.
• ֺFactory approval and Quality Control: Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions.
• ֺField proven designed 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 surge event during pipeline fillingor column separation.
• ֺService Ports fitted: ¹/8”;DN3 or ¼”;DN6 plug (code P) for pressure gauge connection, check point or test drain for airvalve 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 ֺ

• 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.
