McTighe Industries offers an electric motor operated, positive open, positive close fluid control valve to prevent exceeding the separator spill containment capacity. The valve is coupled with the time-tested McTighe level sensor system to stop fluid flow through the separator when the unit is flooded with product. The maximum oil spill capacity of a standard McTighe oil-water separator is 80% of the total vessel volume. The valve is recommended on applications where there is the possibility of an oil spill that exceeds the spill capacity rating of the oil-water separator.

Another application for the valve is to stop separator flow during the few minutes needed for product pumpout operations. This assures a greater product purity and limits the times the product pump must cycle.

When separated product increases to a predetermined level in the separator, the level sensor sends a signal to the control panel activating the electric motor actuator of the valve. An adequately sized valve relay is mounted in the panel for control of the valve.
