Abstract: An independent metering valve circuit includes an actuator, a set of independent metering valves, an independent metering valve pre-compensator, an inverse resolver, and a signal conditioning element. The set of independent metering valves are fluidly coupled to the actuator and configured to independently control a flow of a hydraulic fluid to the actuator. The independent metering valve pre-compensator is configured to control the flow of the hydraulic fluid to the set of independent metering valves. The inverse resolver is configured to receive a first pressure signal from the independent metering valve circuit and a second pressure signal from a load-sense hydraulic system and output a third pressure signal. The signal conditioning element is configured to receive the third pressure signal and output a forth pressure signal configured to control a pump fluidly coupled to the load-sense hydraulic system and the independent metering valve circuit.

Abstract: A valve cover includes a first cover portion, second cover portion, web, and a plurality of bolt holes formed therein. The first cover portion has a first shape. The second cover portion has a second shape that is different from the first shape. The web connects the first cover portion to the second cover portion. The valve cover has a long axis disposed along the first cover portion, web and second cover portion. A first bolt hole of the plurality of bolt holes is offset from a remainder of the plurality of the bolt holes.
