1. Introduction
1.1 Intended users of the product
The product should be handled by users with basic knowledge of hydraulics and electrics (who
are at least equivalent to a class-2 hydraulic system control engineer, who have received
technical training from YUKEN KOGYO, or who can fully understand the contents of this
manual) or under the supervision of such personnel.
1.2 Intended purpose
The valves are closed loop, high response type proportional electro-hydraulic directional and
flow control valves with OBE (on-board electronics). 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 spool type 3C2L is suitable for position control (2%
overlap).
