A fluid system and method of operation provides flow force compensation and load sense functions. Each work circuit includes an actuator, a control valve, and a first valve. A valve element of a control valve includes main metering orifices sized and shaped to provide flow force compensation. A load sense check valve associated with a load pressure signal conduit is downstream of the load check valve. The load pressure signal conduit of each work circuit is in fluid communication with one another, and a greater of the load signal pressure of the work circuits is communicated to the load sense check valve of the other work circuit. The control valve associated the lesser load can permit flow forces to reduce the effective area of the orifice, which increases the pressure difference across the valve to maintain approximately constant flow to the actuator.
