Automatic Separation Valve TOO


The BERMAD model TOO is a specific gravity sensitive valve, for the automatic draining of a heavier fluid from a lighter fluid.

Commonly used for the draining of water accumulated in the bottom of petroleum product storage tanks where the stored medium has a lower specific gravity than that of the accumulated water.

The TOO valve should be opened to initiate dewatering. When all the accumulated water has drained from the storage tank the presence of product will be sensed by the TOO valve and it will automatically and immediately shut off drip tight. When fitted with the optional factory

fitted limit switch, a signal can be sent to a remote valve position monitoring system, signaling that the valve is closed.

It is well suited for use with storage tanks containing Gasoline, Gas Oil, Jet Fuel, Kerosene, Diesel Oil, Crude Oil and all Petroleum products including Light Crude Oil. The TOO uses a simple and reliable principle with a straightforward and compact construction, designed to require

minimal maintenance, and to last the lifetime of the tank.

Using the TOO can save product loss, work hours, and increase available tank storage space. It is environmentally cleaner, safer, more reliable and efficient compared to manual or other methods

Each valve is assembled and tested in the BERMAD ISO 9000 and

9001 certified manufacturing plant.

Introduced to the industry in 1997 the TOO is a time proven product in use in over 20 countries worldwide and backed by the Global Service Network of BERMAD.
