FALCO 100 / 300 VAPOR CONTROL VALVE (VCV)® for Soil Vapor Extraction
Falmouth Products Vapor Control Valve (VCV) is installed inline on the vacuum side of the extraction blower. The VCV enables the FALCO to start up, operate automatically, and cooperate with the temperature controllers to regulate input vapors. The VCV minimizes power use by accurately maintaining maximum input concentration consistent with the heat recovery adjustment.
The VCV includes a valve body with two valve seats, valve disc, and a gear motor. The motor progressively opens and closes the valve in response to input from the oxidizer’s three temperature controllers. The valve simultaneously regulates dilution air and source vapors by positioning the valve disc. Controller rate alarms regulate how quickly the VCV introduces vapors. A solenoid valve provides rapid introduction of dilution air, regardless of valve position. The VCV automatically returns to its closed position each time FALCO power is cycled.
