A system comprising: one or more valve assemblies, each having: a conduit defining an inlet configured to be in fluid communication with a pressure source, an outlet configured to be in fluid communication with a respective hydraulically-actuated device, and a vent configured to be in fluid communication with a reservoir and/or a subsea environment; and one or more valves in fluid communication with the conduit and including: an electrically-actuated first valve that is movable between a first valve first position in which the first valve permits fluid communication from the inlet to the outlet and a first valve second position in which the first valve prevents fluid communication from the inlet to the outlet; and a second valve that is movable between a second valve first position in which hydraulic fluid that flows through the second valve from the first valve is directed to the outlet and a second valve second position in which hydraulic fluid that flows through the second valve from the first valve is directed to the vent; and a processor configured to actuate at least one of the valve assembl(ies) between: a first state in which the first valve is in the first valve first position and the second valve is in the second valve first position; and a second state in which the first valve is in the first valve first position and the second valve is in the second valve second position. one or more valve assemblies, each having: a conduit defining an inlet configured to be in fluid communication with a pressure source, an outlet configured to be in fluid communication with a respective hydraulically-actuated device, and a vent configured to be in fluid communication with a reservoir and/or a subsea environment; and one or more valves in fluid communication with the conduit and including: an electrically-actuated first valve that is movable between a first valve first position in which the first valve permits fluid communication from the inlet to the outlet and a first valve second position in which the first valve prevents fluid communication from the inlet to the outlet; and a second valve that is movable between a second valve first position in which hydraulic fluid that flows through the second valve from the first valve is directed to the outlet and a second valve second position in which hydraulic fluid that flows through the second valve from the first valve is directed to the vent; and a conduit defining an inlet configured to be in fluid communication with a pressure source, an outlet configured to be in fluid communication with a respective hydraulically-actuated device, and a vent configured to be in fluid communication with a reservoir and/or a subsea environment; and one or more valves in fluid communication with the conduit and including: an electrically-actuated first valve that is movable between a first valve first position in which the first valve permits fluid communication from the inlet to the outlet and a first valve second position in which the first valve prevents fluid communication from the inlet to the outlet; and a second valve that is movable between a second valve first position in which hydraulic fluid that flows through the second valve from the first valve is directed to the outlet and a second valve second position in which hydraulic fluid that flows through the second valve from the first valve is directed to the vent; and a processor configured to actuate at least one of the valve assembl(ies) between: a first state in which the first valve is in the first valve first position and the second valve is in the second valve first position; and a second state in which the first valve is in the first valve first position and the second valve is in the second valve second position. a first state in which the first valve is in the first valve first position and the second valve is in the second valve first position; and a second state in which the first valve is in the first valve first position and the second valve is in the second valve second position.
