Separation valve

A separation valve for separating immiscible liquids of different specific gravities, comprising:

• a container having a chamber for receiving said liquids;
• an outlet at the lower end of the container for outletting the liquid of higher specific gravity;
• a valve opening between said chamber and said outlet;
• and
• a floatable valve member within said chamber movable towards and away from said valve opening, said valve member being of a weight and volume such as to be at least partially immersed in the liquid of lower specific gravity in said chamber and to float in the liquid of higher specific gravity, and thereby to close said valve opening when the liquid of higher specific gravity within said chamber has exited therefrom via said outlet,
• wherein said chamber includes a vertical guide for guiding the movements of said floatable valve member,
• wherein said vertical guide is of cylindrical configuration and is formed with a plurality of openings along its length to establish communication between its interior and said chamber,
• and wherein said container has an open upper end which is closed by a cover formed with a circular recess in its inner face centrally thereof for receiving and securing the upper end of said vertical guide.
