A high-pressure valve comprises an intake channel and two outlet channels. Further, an actuator is provided for opening and closing the outlet channels. According to the invention, the actuator is provided with a connection channel. The connection channel makes it possible to reduce a pressure difference between the intake channel and the closed outlet channel prior to opening the outlet channel. For this purpose, a channel opening will be opened by displacement of a control element arranged in the connection channel.
