C.I.Agent® HFF Oil Stop Valve

C.I.Agent® Hydrocarbon Flow Filter (HFF) Oil Stop Valve is a secondary containment solution that filters and processes wastewater removing hydrocarbons to a non-detectable level and automatically shuts off in the case of a major hydrocarbon release.

All secondary containment systems have to incorporate some type of drainage system to evacuate wastewater. The HFF Oil Stop Valve is ideal for this application as each HFF is designed for site-specific oil containment applications and meets Federal SPCC mandates.

HFF flow rates vary by size of filter, vertical or horizontal mount and the head pressure.

The HFF Oil Stop Valve uses C.I.Agent® Oil Solidifying Polymer technology to capture all organic hydrocarbons, including the most volatile organic compounds, such as sheen, gasoline, diesel, refined oils and more. Each HFF Oil Stop Valve is capable of processing wastewater at the pre-determined rate specified by the customer.

All HFF Oil Stop Valves come with a pre-filter to trap and eliminate unwanted sediment and debris before it gets to the main filter, which extends the life of the filter.
