Abstract
A valve () comprising a housing (), a valve filter media () and an actuator (). The housing () defines a chamber () having an inlet () and outlet (). The media () is positioned within the chamber () such that liquids flowing between the inlet () and outlet () pass through the media (). The valve filter media () is formed of a material which can absorb hydrocarbons, causing the media () to change its material properties thereby restricting the flow of liquids through the valve () and increasing the pressure differential across the media (). The actuator () has at least a portion positioned within the housing chamber (). If the pressure differential across the media () exceeds a predetermined threshold, the media () bears against the actuator () causing the actuator () to restrict the flow of liquids through the valve ().
