Abstract: A valve is provided for a hydraulic system having a source of pressurized fluid, a fluid actuator, and a proportional pressure compensating valve. The valve has a bore in fluid communication with the source and the fluid actuator. The valve also has a valve element disposed in the bore and movable between a flow blocking position and a flow passing position to selectively fluidly communicate the source with the fluid actuator. The valve also has a valve signal passageway disposed within the valve element and configured to be in fluid communication with a pressurized fluid having a signal pressure indicative of pressure supplied to the fluid actuator. The valve further has first and second orifices disposed within the valve element in fluid communication with the valve signal passageway and the bore. The valve signal passageway is configured to communicate the signal pressure with the first and second orifices.

Abstract: Consistent with an aspect of the disclosure, a method for controlling a hydraulic cylinder is provided. The hydraulic cylinder is provided with a chamber and configured to receive fluid from a valve. The method includes receiving a user input and determining a desired velocity of the hydraulic cylinder in accordance with the user input. In addition, the velocity of the hydraulic cylinder is measured and a position of the valve is determined in accordance with the desired velocity of the hydraulic cylinder and the measured velocity of the hydraulic cylinder. The method further includes determining a desired force to be applied to the valve in accordance with a difference between the desired and measured velocities of the hydraulic cylinder, and actuating the valve in accordance with the desired force to thereby inject the fluid into the chamber and move the hydraulic cylinder.
