More Information
Summary:The present invention relates generally to a device for sealing of an electric drive for an hydraulic valve. The device comprises: -at least an electrically driven actuator (13) for controlling the flow through an hydraulic valve (10); - connection cables (32) for connecting the actuator (13) with control signals from an electronic box (31); and - an at the top of the actuator (13) placed sealing device (20) for sealing of the connection cables connection to the actuator; The device is characterized in that the sealing device comprise a lower part (21) attached to the actuator (13) and which sealingly abuts the actuator's periphery, and an upper part (22) separated from the lower part, for housing the connection cables (32) connection with the actuator and sealingly connects to the lower part (21).
