TOO
Bottom Oily-Water Drainage Valve
The TOO valve is designed to drain accumulated water from the bottom of hydrocarbon storage tanks and automatically stop when hydrocarbon reaches the calibrated float.
Self-operated valve for draining accumulated water from the bottom of hydrocarbon storage tanks.
Accumulated water is drained from the tank bottom through the TOO valve. The valve remains open during water drainage and closes automatically when hydrocarbon reaches the calibrated float, helping prevent product discharge without the need for continuous operator monitoring.
HOW IT WORKS
Water Drainage
Accumulated water is drained from the bottom of the storage tank.
Hydrocarbon Detection
The calibrated float responds when hydrocarbon reaches the valve.
Automatic Shutoff
The valve closes automatically to help prevent hydrocarbon discharge.

TOO VALVE — KEY INFORMATION
DIMENSIONS & BASIC INSTALLATION
DIMENSIONS & BASIC INSTALLATION
780 mm x 580 mm x 510 mm x 435 mm
30.1 in x 22.8 in x 20 in x 19 in
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.
