This is a proportional, non-compensated, 3 position 4 way, directional ow
control solenoid valve, with closed-center spool.
This is an electro-proportional directional control using a 3-Position, 4-Way
design for directional control of hydraulic cylinders and motors. For load-
independent ow control, apply with a pressure compensator, like CP701-4
(see Example Circuit). Port 1 should be used as the tank port, with a
maximum back-pressure of 150 bar. The highest return ow coming from a
cylinder should be connected to Port 2.
Use the available Comatrol Adapter Block (CP12-4-D05 or CP12-4-
D05-PC) to help test and replace proportional CETOP D05 - available in
compensated or non-compensated.
Note: For optimal performance install with the solenoid valve below the
tank oil level in the horizontal position, reducing the chance for trapped air
in the valve.
