Notes
The through flow is depended on
the spool type.
Notes
1.
The solenoid controlled pilot operated directional valve must
be used with hydraulic solenoid directional valve. Please use spool 2B2 for
single coil of G04 solenoid valve; for double coil solenoid valve, please chose
spool 3C4.
2.
The internal drain pressure must be kept 5kgf/cm² higher than
the tank line. Please choose external drain type to insure proper pilot
operated shifting.
3.
The maximum flow varies with the type of the valve. If don’t
magnetize, the flow rate of 3C6, 3C60 or 3C5 spool type is smaller when the P
hole and T hole interlinked.
4.
The external pilot pressure of the external pilot type must exceed
5kgf/cm² or more.
5.
The G04 & G06 valves do not contain a back pressure check
valve. For open center spools, please install at time of plumbing.

The features
1.
G02 wet pin solenoid pilot valve will control the slave
valve.
2.
For internal or external pilot or drain, a simple plug
conversion is required.
3.
The solenoid controlled pilot operated directional valves are
suitable for the installation of surface should be kept under 3.2z surface.
4.
Solenoid directional control valve with Adjustment type is
available for selection.
5.
Anti-rust by the phosphate on the surface, and the body
appearance of the valve is black.
6.
The size of spool, G04 type: Φ25mm.
How to use
1.
If you are using the interior draining type, must keep the
pressure of reflux and over 5kgf/cm²; and the pressure of reflux is higher than
the pressure of brake, please choose the exterior draining type.
2.
If you are using the exterior draining type, must keep the
pressure of brake is higher than the pressure of reflux and over 5kgf/cm². And
please installing the check valve.
3.
Please select the external pilot type, if the spool types of
the slave valve will be 3C3, 3C5, 3C6 or 3C60.
4.
The valve can change the type of piloting and draining.
