Features
q
This modular valve is used to control
actuator speed and for other flow con-
trol valve applications.
w
A wide range of models are available
for A and B port control, A or B port
control, and P or T port control.
e
Maximum Operating Pressure: 25,
35MPa {255, 357kgf/cm

}
Specifications
zIn a 03 size application where con-
trol differential pressure is large,
use of an H type makes adjustment
easier.
xNote that a sub plate and installa-
tion bolts are not included. See
pages D-90 through D-95 if these
items are required.
c04 series modular valves do not
have an L (DR
2) drain port, so they
cannot be used in combination with
pressure center type solenoid
valves (D).
