Automatic Separation Valve Type:TOO
ECO valve model TOO is a specific gravity sensitive valve,
for automatic draining of a heavier liquid from a lighter liquid.
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.
When all accumulated water has drained from the storage tank
the presence of stored product will be sensed by the TOO valve
and it will automatically and promptly shut off.
When fitted with the optional factory limit switch,
a signal can be sent to a remote valve position monitoring system,
signaling that the valve is closed.
Basic Installation instructions:
In a vertical position
(to be performed using a level measuring device
to ensure accuracy)
At the lowest available point of the tank
Firmly positioned and held securely
As close to the storage tank as possible
Ensure that the size of the manual drain valve between the storage tank
and the Separation Valve is at least as large as the inlet flange of the Separation Valve.
If a pipe is to be connected to the outlet of the Separation Valve,
make sure it is as short, straight and horizontal as possible.
This will allow undisturbed drainage
and will prevent the development of undesirable suction.
In cases where a downward slope is unavoidable,
allow for an air gap (vacuum breaker) in the drainage pipeline.
Make sure that the TOO valve and ancillary parts are thoroughly secured.
