[YUKEN] — LSVG-03EH On-Board Electronic Direct Linear Servo Valve
Family ID: YK-LSVG03EH
On-board electronic (OBE) type direct-operated linear servo valve, realizing the 'high precision, simple, convenient' concept of the LSVG and LSVHG-EH series in a direct-operated form. Hysteresis 0.1% or less; step response 3 ms; frequency response up to 260 Hz. Operates from a DC 24 V supply with command-signal input only; built-in amplifier with fault-diagnosis indicator. Usable to NAS 1638 class 10 (ISO4406 21/19/15). Safety device PABT / PBAT / neutral; connector 6+PE / 11+PE; dry (Y-port) or wet (no Y-port) type — selectable per order.
