These valves behave like pilot operated relief except there setting is controlled by solenoid current.  More current equals more pressure.  They can be applied in system where varying pressure control is required by some electronic means, fan drives for example.  Available in capacities low to 760LPM.  Talk to HCV about your proportional requirement.
