Abstract: A new flow control principle and a pressure and flow double close loop control algorithm are proposed. This makes it possible to control pressure and flow with only one proportional relief valve instead of one three-way proportional flow and one proportional relief valve. The experimental investigation shows that the valve has excellent dynamic and static performance.

Key words: Control, Flow, Pressure, Proportional relief valve
