Features and Benefits of Our Oil Stop Valves

Our oil stop valves are designed to meet Spill Prevention Control and Counter Measures (SPCC) requirements to ensure compliance with industry standards. They can be easily integrated into existing storm sewer pipes and structures for secondary containment.

Key features of our oil stop valves include:

  • Dependable operation with long product life
  • Passive design with a stainless steel float
  • No on-site operator required; only periodic inspections
  • No electrical power to operate
  • Slave valve for easy maintenance
  • Self-opening feature to mitigate the effect of sump water evaporation
  • Standard valve sizes with fully adjustable float

Preventing Oil Spills and Environmental Damage

Our oil stop valves are designed to prevent the release of oil and fuel into the environment or wastewater systems. They ensure that stormwater drains and runoff do not become contaminated with oil or fuel to protect air quality, the environment, and drinking water sources.

Oil spills can have catastrophic consequences, impacting everything from wildlife to local economies and tourism. Our oil stop valves serve as an automatic failsafe, differentiating between oil and water using the specific gravity principle.

With only one moving part (the float), our valves are low-maintenance and reliable. If oil/fuel is introduced in the chamber or vault the float will drop. It will sit onto the flange shutting off flow to the discharge port.

Our oil stop valves operate on the principles of buoyancy, with a ballasted float weighted for a specified gravity. In water, the float will keep the valve open, while an accumulation of oil will cause the float to sink and close the valve.

The housing for our oil stop valves is made from non-corrosive PVC (low risk of fire) or stainless steel (high risk of fire), providing greater design flexibility and pricing options. They can be installed below ground and in line with your piping system, as well as in pre-assembled concrete manholes or vault designs.
