The purpose of the Air Flow Control Valve is to meter air flow at a set rate accomplishing several needs.  This valve creates a consistent airflow to biosparge wells that feed air into the subsurface for bioremediation. The consistent airflow permits low flow of air, which in turn prevents channeling of the air path through the soil. With a balanced air flow over the entire system, demand on the compressor is minimized.  This control valve allows air flow to remain in the patented (#6,464,005) range of 5 to 40 cubic feet of air flow per hour (CFH).

The Air Flow Control Valve is superior to other valves in that there is an adjustment mechanism for ±25% adjustment from the set point of 20 CFH. A flow meter is built into the valve so that measurement is automatic with valve inspection. The Air Flow Control Valve is built so that it will enable biosparge wells to flow consistently, regardless of groundwater elevation changes, barometric pressure changes or compressor flow variations.

The Air Flow Control Valve encompasses the principles of air pressure, venturi restriction, piston with double cylinder, spring adjustment and metered air measurement. The body of the Air Flow Control Valve and flow meter is made of clear Polycarbonate Lexan 141 high impact material.  This allows a visual inspection of working parts to determine the need for cleaning and to see the ball in the flow meter.

A dual valve design for the Air Flow Control Valve creates compactness for installation; cost saving over single valves designs and reduces material requirements.  It also allows the connection of valves together in series.

The Air Flow Control Valve was designed for Subsurface Metabolism Enhancement or SME, a hydrocarbon bioremediation method. When SME is appropriately applied, remediation will occur quickly and with a minimum of site disturbance. The Air Flow Control Valve reduces maintenance on the SME system and prolongs the life of the compressor, which in turn reduces the cost to remediate.
