Bermad - Model A10 - Automatic Air Valve

BERMAD A10 is a high quality automatic air release valve that allows efficient release of air pockets from pressurized pipe lines. With its advanced design this valve provides excellent protection against air accumulation with improved sealing in low pressure conditions.

Features & Benefits

• Large diameter automatic orifice: Higher flow rates.
• Dynamic sealing: Prevents leakage under low pressure conditions(1.5 psi; 0.1 bar).
• The boss on the base can be tapped with a thread for pressure gauge connection, checkpoint or test drain for air valve function.
• Compact, simple and reliable structure whose parts are fully corrosion, chemical and fertilizer resistant: Lower maintenance and increased life span.
• Factory approval and Quality Control: Performance and specification tested and measured with a specialized test bench.

Additional Features & Accessories

• Service Port Port fitted with 1/8” plug (code P)
• Test point (code T)

Typical Applications

• Irrigation Control Heads: Protection against air accumulation at filtration and fertilization stations and downstream of main control valves.
