Oil Stop Valves

EVSL Oil Stop Valves were developed as a means of dealing with above ground fuel tank bunds which fill with rainwater and need to be emptied.  Most tank bunds come fitted with a drain valve, but in many cases these seemed to be left open, which defeats the purpose of the bund.

The oil stop valve fits on the inside of the bund and allows water to be discharged but retains any oil up to a density of approximately 0.90, i.e. lighter than #4 fuel oil, thus covering diesel and lube oils but not medium fuel oil.  A 25mm female socket with 65mm clearance to the floor of the bund is required for fitting.

These units are ideal for use in remote sites where there is no one to monitor water levels in the bund.
