Abstract: A hydraulic valve for connecting a first fluid-conducting pressure line to a second fluid-conducting pressure line in an actuator for activating a high- or medium-voltage circuit breaker includes a housing with a first channel inlet for attachment to the first pressure line, and with a second channel inlet for attachment to the second pressure line, and a cavity situated between the first and the second channel inlet. The hydraulic valve includes a sealing body which can move in the cavity and has a circumference which is greater, at least at one point, than the respective circumference of openings adjoining the cavity, of the first and the second channel inlets. The sealing body is geometrically matched to the cross-section of these openings to completely seal the openings when seated. First and second spring elements connected to the sealing body project into the cavity in the relaxed state.
