SERIES■ Shockless Type Proportional Electro-Hydraulic Directional and Flow Control Valves
These valves are well accepted by industrial users as shifting time adjustable type shockless valves. By employing the basic
design concept of the “G series solenoid operated directional valves”, we have been successful developing the shifting time
adjustable shockless valves with high performance which makes the speed setting possible at any high speed operation.
In combination with the newly developed digital amplifiers, the further enhancement of maneuverability and repeatability of thevalves can be realized.

3C40● ‌During piping work, special care should be taken so that the tankport “T” is constantly filled with hydraulic fluid. Because backpressure is applied, using a check valve whose cracking pressure isabout 0.04 MPa is recommended. Also, connect the tank port piping
directly to the oil tank, but do not connect it other piping. For thisreason, be sure to immerse the pipe end in fluid.
● ‌‌In the event of an electrical failure or other emergency, the flow rate
and oil flow direction can be switched by screwing in the manualadjustment screw. After operation, be sure to return the manualadjustment screw completely to the original position.
