The Gardena control valve provides more flexibility when watering the garden. It can be connected to one of the two outlets of a Y-piece (sold separately). With just one hand, the valve allows for stepless regulation of the water flow or complete shut-off. Once the water is stopped, the attachment can be changed on-site without needing to turn off the water at the tap. Connecting a sprinkler to the control valve is particularly practical for garden irrigation, as the valve allows for adjustment of the water flow and thus the range of the spray. Thanks to its UV and frost resistance, it can be used year-round.
