6. The lowering speed of the lower
link is proportional to the applied
weight but can be controlled by ad-
justing the draining passage of the
hydraulic fluid. (See “Lifting arm

KIOTI
supplies two types of the
double acting valves by region: self-
return type and detent type.
For the self-return type double act-
ing lever, it returns to its original
position to block the hydraulic uid
when it is pushed/pulled and then
released. However, this type of
double acting valve lever should be
pulled or pushed continuously for
operation which is suitable for an
implement with a short operating
time, such as the hydraulic cylinder.
For the detent type double acting
valve lever, it keeps its position af-
ter it is pulled or pushed to a certain
position. Therefore, it is not neces-
sary to hold the lever to a certain
position which is suitable for an
implement with a long operating
time, such as the hydraulic motor.
