Bermad IR-C30-C Ductile Iron Combination Air Valve (PN16)

The BERMAD C30C is a high-quality combination air valve, designed for a variety of irrigation 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, this double orifice valve provides excellent protection against air accumulation and prevents vacuum formation, with improved sealing in low-pressure conditions (less than 1m). The valve is a plastic shell body valve with a Ductile Iron outer shell cover, offering the security of a metal body. Options that can be added to the 50mm valve are Surge protection, Assisted closure or Inflow protection kits.

FEATURES

• 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, checkpoint, or test drain for air valve function.
• Threaded Side outlet (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 life span
• Design in compliance with functional standards and water service standards.
• Factory approval and Quality Control: Performance and specification tested and measured with a specialized test bench, including vacuum pressure conditions.

MATERIALS

• Ductile Iron (code C30C), coated with Fusion Bonded Epoxy.
• Float Assembly: Polypropylene, Glass Reinforced Nylon.
• Elastomers: EPDM, Optional - Viton.

OPERATIONAL DATA

• Minimum operating pressure: 1.5 psi; 0.1 bar
  Maximum operating pressure: 230 psi; 16 bar
  Media and operating temperature: Water 1-60°C.

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.
