4 EDG series proportional pressure and flow control valves echnical specification Flow and pressure Mounting EDG-03 (flow control) EDG series proportional pressure and flow control valves adopt two electrical loops to control pressure and flow of hydraulic system respectively. Using very small pressure drop to track load pressure and control the pump pressure, it is an energy-saving valve.
