    Abstract: The invention relates to a method for two-step separation of water, salt and particles from a hydraulic fluid by the use of a control unit. The hydraulic fluid is carried into a return oil tank with an electrostatic coalescer provided with a high-voltage transformer with direct current to two electric grids whose electrostatic field gathers water into drops which settle into a collecting tank. The hydraulic fluid is circulated to a filter module for removing any remaining water, salt and particles in filter elements connected in parallel, having hygroscopic cellulose fibers which swell until saturation, the swelling being measured by a sensor measuring the degree of saturation, alternatively conductivity.

    Abstract: A device for an inert gas installation (5) on a floating vessel, comprising one or several tanks (1) arranged in a manner allowing filling of an explosive liquid (11) via suitable means (13, 14) associated therewith, and/or a gas (12), wherein an air inlet system (3) is connected to the tank (1), wherein the inert gas installation (5) is provided with a shutoff valve (51) arranged to automatically allow closing of an inert gas supply conduit (52), wherein the tank (1) is provided with a sensor (53) arranged to respond to a defined, ambient moisture and pressure level, the sensor (53) also being connected to a valve control system (7), thereby providing control signals to the valve control system (7). The invention also concerns a method of using the device.

    IPC: F16K31/40

    Abstract: An actuator for a pilot for a hydraulic control valve including a direct-current servo-motor (1) provided with a high-ratio gear (4) and arranged to be operated by a battery (2) with an associated battery charger (13), and an oil return port (10), a pilot port (11) and a hydraulic supply (12) and via the gear (4), the servo-motor (1) is arranged to move a valve stem (5) which bears via a first valve ball (7) on a spring-loaded pilot needle (8) which bears, opposite the first valve ball (7), on a second spring-loaded valve ball (7), a spring and a return spring (9) being arranged to move the valve balls (7) towards the pilot needle (8), and a microprocessor with an associated controller (3) being arranged to determine the position of the valve stem (5) by registration of the rotational position of the servo-motor; and, if a control signal is interrupted, the controller (3) is arranged to drive the valve stem (5) into a predetermined position by means of current from the battery (2).
