EDG valves consist of a small DC solenoid and a direct-acting relief valve. They serves as a low flow rate hydraulic system or a pilot valve for electro-hydraulic proportional control valve and controls the pressure in proportion to the input current. Note that these valves are used in conjunction with the applicable power amplifier.

EFBG including relief and flow control valves are energy-saving valves that supply the minimum pressure and flow necessary for actuator drive.

Since this valve controls the pump pressure by following the load pressure while keeping the differential pressure minimized, it serves as a low power-consumption energy-saving, meter-in, controlled flow control valve.

Further, since a temperature compensation function is incorporated, this valve provides consistent flow control without respect to the fluid temperature.
