Product Description

BERMAD A30 is a high-quality automatic air release valve that allows the efficient release of air pockets from pressurized pipelines. With their advanced design, these valves provide excellent protection against air accumulation with improved sealing in low-pressure conditions.

Features & Benefits

  • Large diameter automatic orifice: High flow rates.
  • Dynamic sealing: Prevents leakage under low-pressure conditions (model A30 - 1.5 psi; 0.1 bar)
  • Compact, simple and reliable structure with fully corrosion-resistant parts: Lower maintenance and increased life span.
  • Design in compliance with EN-1074/4 standard and water service standards.
  • Factory approval and Quality Control: Performance and specification tested and measured with a specialized test bench.

Additional Features & Accessories

  • Service Port fitted with 1 /8” (Code P) for pressure gauge connection, checkpoint or test drain air valve function.
  • Test point (code T)

Typical Applications

  • Pipelines: Protection against air accumulation in high points and long horizontal lines
  • In proximity to control valves and water meters: Prevention of inaccurate pressure regulation and biased readings due to air existence in these devices.
