Drum 4.2.1 “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: ѓ Energy savings: the water inside the drain circuit is not heated. ѓ The detergent does not deposit on the filter body, thus improving the quality of the wash (reduction in mechanical detergent losses). ѓ Better rinsing efficiency.
