The Oil Stop Valve protects waterways from oil or petroleum spills. The passive spill stop valve detects accumulations of oil and activates a valve that positively stops the flow of stormwater and oil upstream from the valve.
Large, unpredictable oils spills can defeat even the most conservatively designed pollution control systems. The OSV is an economical option used to confine hydrocarbon spills to the premises for safe disposal. Contech’s OSV is fabricated from either non-corrosive Stainless Steel or PVC and has only one moving part, the ballasted float. When an oil spill occurs, the float loses buoyancy as the free-floating oil depth increases until it finally seats on the discharge port, closing and confining the spill.
The Oil Stop Valve housing is fabricated from non-corrosive PVC (low risk of fire) or stainless steel (high risk of fire) to provide greater design flexibility and pricing options. It is typically installed below ground and in-line with the piping system and can also be installed in pre-assembled concrete manhole or vault designs.
