A programmable, four way directional control valve, with the versatility to operate in any type of hydraulic system and perform any function, was designed with functional variations to be made in the control software, rather than the hardware. This paper reports on the first reduction to practice, along with the development of a new “inferred flow feedback” concept. The initial prototype has shown promising results, in spite of hardware limitations encountered: flow forces and valve dynamics. Pressure control is especially encouraging, with nearly perfect regulation of pressure across the flow range of the programmable relief valve.
