Circuit Description:

(This circuit is an Electrohydraulic Pressure Control circuit for Linear load. Here, the valve is able to provide pressure down to [0.1 bar] provided the pump flow is small enough relative to the valve flow rating. To obtain accurate pressure control the spool valve should have high dynamic performance and be zero or sligthly underlapped. If these requirements are met excellent accuracy and repeatability can be obtained over a wide range of pressure. [Ref.1]. This circuit matches load1 due to: control mode selected effort and position horizontal .).
