1. A manifold system for providing hydraulic fluid to a first hydraulically actuated device and a second hydraulically actuated device of a blowout preventer, the manifold system comprising:
a first fluid source and a second fluid source separate from the first fluid source such that the first fluid source and the second fluid source may be activated and deactivated independently;
a plurality of inlets configured to receive hydraulic fluid from the first fluid source and the second fluid source;
a first outlet in fluid communication with an actuation port of the first hydraulically actuated device;
a second outlet in fluid communication with an actuation port of the second hydraulically actuated device;
a first subsea valve assembly, the first subsea valve assembly having a main stage valve configured to control hydraulic fluid communication from at least one of the inlets to at the first outlet; and
a second subsea valve assembly, the second subsea valve assembly having a main stage valve configured to control hydraulic fluid communication from at least one of the inlets to the second outlet.
