Float valve A71

for potable waterstainless steelpolypropylene

Overview
BERMAD A71 is an automatic air release valve for efficient evacuation of air pockets from pressurized pipelines. Designed for waterworks applications, the valve improves sealing at low pressure and reduces maintenance through corrosion‑resistant internal parts.

Features & Benefits

• Efficient evacuation of air pockets from pressurized pipelines.
• Dynamic sealing that prevents leakage at low pressure (1.5 psi / 0.1 bar).
• Compact, simple construction with fully corrosion‑resistant internal components for reduced maintenance and extended service life.
• Certified for potable water: NSF/ANSI/CAN 61 and NSF/ANSI 372.
• Factory performance verification on a specialized test bench, including vacuum pressure conditions.

Typical Applications

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

Certifications & Testing

• NSF/ANSI/CAN 61 (drinking water)
• NSF/ANSI 372 (lead‑free)
• Performance and specification testing on a specialized test bench, including vacuum conditions
