Check valves with
hydraulic operation for
plate mounting-
KOHU16P
Hydraulically operated
check valve is designed to
allow working liquid passing
in one direction freely (P
2
to P ), and at availability of
1
control signal in the
opposite direction (P to P ).

The valve ensures
hydraulic “locking” of the
hydraulic cylinders , i.e.
providing their stability
under load at neutral
position of the directional
control valve.
