Double Ball Valve
When water is supplied in pump outlets and pipelines, air accumulations that occur in the system, especially at the pump outlets, narrow the passage area of the water and cause its capacity to decrease. Double spherical suction cups are used in places where high efficiency is required to prevent this inconvenience. When water is pressed into the system, the air formed is filled into the suction cup before it is discharged from the holes in the side covers. Then the suction cup fills with water and lifts the balls up and the holes are closed to ensure sealing.
