These valves are closed loop, high response type proportional electro-hydraulic directional and fl ow control valves with OBE (on board electronics). Two direct type models with a maximum rated flow rate up to 80 L/min (@∆P = 1 MPa) are available. The addition of OBE to the well-received ELDFG series valves for simplified wiring offers simple operation and userfriendliness. With closed loop control based on a combination of newly developed compact, powerful solenoids and a LVDT for spool position detection, the valves provide high response, high accuracy, and high reliability equivalent to those of simple servo valves. The zero lap spool type (spool type 3C2L) is suitable for position or pressure control.
