About Roof Drain Spill Stopper
Primarily designed for floating roof storage tank drain systems, tank farm dike drain systems and wastewater treatment facilities, SPILL STOPER remains open during normal operation, allowing rainwater and non-hydrocarbon liquids to flow and drain from the tank or dike area. However, should hydrocarbons enter the liquid flow, the internal sensing characteristics of the SPILL STOPER cause it to close, containing the problem and protecting the environment.
SPILL STOPER has been designed for trouble-free performance. Since this valve is mechanically actuated, replacement of the Hydrocarbon Sensing Element upon repair of the source of the hydrocarbon leak source will reset the actuator. Winter freeze-ups are reduced because the drainage system can remain open due to SPILL STOPER monitoring the liquid flow.
SPILL STOPER Hydrocarbon Sensing Valves are available in 4″ Diameter size, with 150# flanges. The rugged aluminum and stainless steel construction of this full flow valve offers lightweight plus long service life durability and strength. SPILL STOPER makes good economic and environmental sense.
