4.1.1 “ECO-BALL”
ball
valve
The "Eco-ball" valve consists of a sphere
contained inside the tube that connects the tub to
the filter body. Its purpose is to keep the washing
water (contained in the tub) separate from the
water in the drain circuit.
Advantages with respect to a conventional circuit
:
Energy savings: the water inside the drain circuit is not heated.
The detergent does not deposit on the filter body, thus improving the quality of the wash (reduction in
mechanical detergent losses).
Better rinsing efficiency
4.1.2 Ball valve: operating principle
During the water fill and washing phases, the sphere is raised by the water contained in the drain circuit
to the uppermost position, thus preventing water from passing between the tub and the filter body.
During the drain phases, the suction effect
created by the operation of the pump causes the
sphere to move downwards, thus allowing the
water to flow through the drain circuit.
