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
When configuring piping,
ensure that the T port is filled with operational fluid.
3. Manual Adjusting
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).
the valve so the spool axis line is horizontal.
with a Pressure Compensation Valve
the optional pressure compensation kit is recommended when higher
precision flow rate control is required or in high-pressure
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
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.
hydraulic operational fluid contamination so it is at least Class 9.

10. Use an
operational fluid that conforms to the both of the following
temperature: -20 to 70°C. Viscosity: 12 to 400 mm2/s.
recommended viscosity range is 15 to 60 mm2/s.
