1.
Air Bleeding
In order to
ensure stable control, loosen the air vent and bleed air from the valve
before starting operation. For details, see the user's guide.
2.
T Port Piping
When
configuring piping, ensure that the T port is filled with operating fluid.
3.
Manual Adjusting Screw
For the initial adjustment or when there is no input current to the
valve due to an electrical problem or some other reason, the valve can
be operated and valve pressure can be increased by rotating the manual
adjustment screw clockwise ( rightward ). Normally, the manual
adjusting screw should be rotated back fully to the left ( counterclockwise
).
4.
Valve Mounting Orientation
Install the valve so the spool axis line is horizontal.
5.
Combining with A Pressure Compensation Valve
Use of the optional pressure compensation kit is recommended when
higher precision flow rate control is required or in high-pressure
applications.
6.
If pilot pressure exceeds 92 kgf/cm2 (9 MPa) use a modular
type P port reduction valve (MBRV-02-P-1) at a setting of 20 kgf/cm2
(2 MPa).
7.
On a system that requires large brake pressure during deceleration or a
system that uses a vertical cylinder, equip a counter balance valve.
Use a single rod, if the rod exit is not slowed sufficiently, use a
counter balance valve on the rod.
8.
Maintain hydraulic operating fluid contamination so it is at least
Class 9.

10.
Use An Operating Fluid That Conforms to The Both of The Following.
Oil temperature : -20 to 70°C.
Viscosity : 12 to 400 mm2/s.
The recommended viscosity range is 15 to 60 mm2/s.
