HFF Oil Stop Valve
The HFF Oil Stop Valve filters and processes rain water, removing hydrocarbons to a non-detectable level. It automatically shuts off in the case of a major hydrocarbon release.
Hydrocarbon Filter for Oil Containment
All secondary containment systems must incorporate some type of drainage system to evacuate wastewater. The HFF Oil Stop Valve is a hydrocarbon filter ideal for this application. 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 uses Justrite 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 hydrocarbon filter 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 hydrocarbon filter, which extends the life of the filter.

Frequently Asked Questions
How much maintenance is involved with the HFF Oil Stop Valve or VIPOR Oil Filtration Systems?
All filters need some level of maintenance, but compared to traditional oil water separators or similar systems, required maintenance for the HFF and VIPOR is minimal. Always use a pre-filter with the HFF to prevent silt and mud from clogging it. Maintenance will depend on the amount of silt, dirt and hydrocarbon the pre-filter is exposed to.
The maintenance frequency of the VIPOR-SOWF, VIPOR-100 SOWF and VIPOR-SUMP also varies by job site, depending on how much dirt exists in the containment that can clog the pre-filter. Always perform an inspection following a significant rain event.
