Automatic relief valve WW-A30

airfor pipelinesthreaded

Overview
BERMAD A30 is an automatic air release valve designed to efficiently evacuate air pockets from pressurized pipelines. Its compact, corrosion-resistant internal design ensures reliable air discharge and improved sealing at low pressures, supporting stable operation in water distribution and irrigation systems.

Key Features

• Efficient air-pocket release from pressurized lines.
• Dynamic sealing preventing leakage down to 1.5 psi (0.1 bar).
• Compact, simple structure with fully corrosion-resistant internal parts to reduce maintenance.
• Factory-tested performance including vacuum and operational pressure conditions.
• Certified for functional and drinking-water standards.

Typical Applications

• Pipelines: protection against air accumulation at high points and in long horizontal runs.
• Installed near control valves and water meters to avoid inaccurate pressure regulation and biased readings caused by trapped air.

Certifications & Standards

• WRAS (UK)
• ACS (France)
• NSF/ANSI/CAN 61 and NSF/ANSI 372 (USA)
