q The control valves of the following types are
set.
6-spool valve (without service valve)
7-spool valve (6-spool valve with service valve)
This control valve consists of a 6-spool valve
q
(unit type) and a set of service valve. A merge-
divider valve, a variable back pressure valve
and a boom hydraulic drift prevention valve are
installed to it.
q Since all the valves are assembled together
with connecting bolts and their passes are con-
nected to each other inside the assembly, the
assembly is compact and easy to maintain.
q With one spool provided for one work equip-
ment, this control valve is simple in structure.
