Automatic Air Valve Model A31

BERMAD A31 is a high quality automatic air release valve that allows efficient release of air pockets from pressurized pipes.
With its advanced design, this valve provides excellent protection against air accumulation with improved sealing in low pressure conditions.

  • Efficient release of air pockets from pressurized pipe lines.
  • Dynamic sealing – prevents leakage under low pressure conditions (0.02 bar).
  • Compact, simple and reliable structure with fully corrosion-resistant parts; lower maintenance and increased life span.
  • Designed in compliance with EN-1074 / 4 standard and water service standards.
  • Factory approval and Quality Control – Performance and specification tested and measured with specialized test bench.

Typical Applications


  • Pipelines – Protection against air accumulation in horizontal or low slope lines and road / river crossings.
  • I n proximity to control valves and water meters – Prevention of biased readings and inaccurate pressure regulation due to air flow through these devices.
  • Industrial and residential networks – Protection against air accumulation.
