Mobile equipment manufacturers continue to be faced today with the ever pressing demand for increased productivity from their hydraulic machines. The on-off type of hydraulic control valves are not accurate enough and do not have the controllability required for increased production rates. The requirement is for valves that smoothly meter flow as well as control direction, without excessive power losses. Further, because of the continued emphasis on operating ease and flexibility of hydraulic system installation, there is need for simple and reliable remote controls that are compatible with existing hardware.This paper presents the performance requirements for remotely controlled mobile hydraulic valves, and describes how they are met by a new family of pressure-compensated proportional valves with six remote control options: mechanical (push-pull cable), hydraulic, pneumatic, electrical, fiber-optic, and radio.
