| BERMAD Mining Mining COMBINATION AIR VALVE Model MN-C50 (For Non-Clean Fluids) BERMAD C50 is a high quality combination air valve for a variety of non-clean mining piping systems 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. The elongated body and lower float prevent the fluid to be in contact with the upper mechanism. With its advanced aerodynamic design, double orifice and Surge Protection device (optional), this valve provides excellent protection against air and gas accumulation and vacuum formation with improved sealing under low pressure conditions. C50-P Specially designed for non-clean (with suspended solids) fluids used in mining such RAFF, ILS & PLS solutions for copper; cyanide barren and pregnant solutions for gold; seawater for desalination plants; slurry, pulp and concetrate lines. Straight flow body with large diameter automatic orifice: Higher than usual air flow. Aerodynamic, full-body kinetic shield: Prevents premature closing without disturbing air intake or discharge. Dynamic Sealing: Prevents leakage under low pressure conditions (0.8 psi; 0.05 bar). Elongated body design: Prevents solids from making contact with valve’s operating parts. Compact, simple and reliable structure with fully corrosionresistant internal parts: Lower maintenance and increased life span. Two service ports: Enabling back flushing and drainage. Threaded Side outlet (2"; DN50) for connection of Surge Protection (SP) or Inflow prevention (IP) devices. Factory approval and Quality Control: Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions. Additional Features & Accessories ■ Surge Protection: Anti-Slam feature for smoother operation, preventing damage to the valve and the system. C50-SP Inflow Prevention: Prevents intake of atmospheric air in cases where this could lead to damaged pumps, required re-priming, or disruption of siphon. C50-IP Drainage Valve (code Z). Pumping stations: Air relief, vacuum and surge protection. Pipelines: Protection against air accumulation and vacuum formation at peaks and slope change points. Water hammer: protection against vacuum formation during down-surge stage in systems affected by water hammer phenomena. All images in this catalog ar
