Oil Stop Valves

A BULK SPILL PREVENTION DEVICE

The purpose of OWS TECH’S oil stop valve is to contain bulk oil/fuel spills to their designated areas while allowing storm water to drain in non-spill conditions thus keeping the containment area available for the purpose in which it was intended. This completely automatic fail safe valve knows the difference between oil and water based on the specific gravity principle. Our unique oil stop valve is designed with only one moving part, a weighted cylinder which floats in water and sinks/closes in the presence of oil/fuel with a specific gravity of 0.95 or less. OWS TECH recommends the oil stop valve for any application where bulk oil/fuel is stored and could unexpectedly enter the environment. Please see below for installation options and valve types.
