Valve System
Description
The Bambi MAX uses a tubular type valve with seals located on the top and bottom of the tube. When in
the default closed position, the seals make contact with top plate and bottom ring of the valve assembly.
When in the open position, the tube is raised allowing water to flow between the bottom of the tube and the
base ring and then through the opening in the base ring.
Movement of the valve tube is controlled by an actuator and drive cable system. The actuator is mounted
on the top plate and consists of a drive motor, reduction gearing and a cable drum. The cable drum can be
rotated clockwise or counter-clockwise depending on the direction of the motor.
One end of the drive cable is attached to the cable drum. The cable is routed down around the deflector
sheaves at the base of the valve and back up to the cable drum where the other end is terminated forming a
closed loop. The drive cable is also attached to a horizontal lift bar which itself is attached across the lower
end of the tube.
When the motor and cable drum is rotated clockwise, the drive cable pulls up on the lift bar, opening the
valve. When the motor and cable drum is rotated counter-clockwise, the other end of the drive cable pulls
down on the lift bar via the deflector sheaves, closing the valve. It is normal for there to be slackness on
the non-tension side of the cable.
