Air and Vacuum Release Valves

The exclusive AR Series, plastic and metal manufactured products offer outstanding features and advantages:

• Perfect sealing under very low system pressure.
• High Air flow capacity.
• Patented operation together with smart design.
• Simple, compact and reliable product.

BERMAD AR Series air and vacuum release valves include four basic models:

• 1” Automatic pressure air release valve (Model 01-ARA), for the automatic release of entrapped air pockets from pressurized systems.
• 2” Kinetic air and vacuum release valve (Model 02-ARK), with large orifice, for the release of large quantities or air from filling pipelines and for admitting air into quick-draining pipelines to prevent vacuum damage.
• 2” Combination air and vacuum release valve (Model 02-ARC), in which the features of the two previous models are incorporated in one single valve body, for safe pipeline filling and draining and for releasing air pockets during system operation.
• 1/2” Vacuum breaker (Model ARV), prevents drip lines from clogging in tough topographic conditions and in sub-surface drip-irrigation system.

Features

• Only one or two moving parts, depending on model
• Corrosion-resistant construction
• Pressure-balanced float, free of distortion or collapse
• Special drip-tight dynamic seal
• Exclusive kinetic design prevents floats from being blown shut
• Perfect sealing under system pressure as low as 0.1 bar, 1.5 psi
