[Yuken] — EFCG-02 40Ω Proportional Flow Control Valve with built-in check valve (E series, 20.6 MPa, size 02)
Family ID: YK-EFCG40-02
40Ω Series Proportional Electro-Hydraulic Flow Control Valves. E-series current-driven valve: set flow changes continuously in proportion to the input current, so system flow can be remotely controlled from a power amplifier; pressure- and temperature-compensated, so set flow is unaffected by load pressure or oil temperature; built-in check valve allows free reverse flow regardless of control current. Suited to shock-free start/stop/speed-change of actuators. Use with a dedicated Yuken power amplifier. Sub-plate mounting, valve size 02. Max operating pressure 20.6 MPa, max adjustable flow 10 / 30 L/min, rated current 600 mA. Coil resistance 45Ω (40Ω series), hysteresis 5%. Optional pressure-compensation piston opening-adjustment screw (N).
