BERMAD A30 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.
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.
Principles of Operation
During pressurized operation of a pipeline, air accumulates in the upper part of the air valve chamber, causing the float to gravitate downwards. This in turn cases the automatic orifice to open, releasing the accumulated air. Once the air is discharged, the water level and float rise, causing the automatic orifice to close.
