Bermad IR-C30-C Combination PN16 Air Release Valve



Bermad IR-C30-C Combination PN16 Air Release Valve

The BERMAD C30 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 product available in 25mm and 50mm.


  • 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.


  • 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 corrosionresistant internal parts; lower maintenance and increased life span.
  • ֺDesign in compliance with functional standard and water service standards.
  • ֺFactory approval and Quality Control: Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions.


  • Pressure Rating: 230 psi; ISO PN16
  • ֺ Minimum operating pressure: 1.5 psi; 0.1 bar
  • ֺ Maximum operating pressure: 230 psi; 16 bar
  • ֺ Media and operating temperature: Water, 33-140°F; 1-60°C
