KIOTI supplies self-return type of the
double acting valves.
For the self-return type double act-
ing lever, it returns to its original
positiontoblockthehydraulicuid
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 operat-
ing time, such as the hydraulic cyl-
inder.
When the relief valve starts to oper-
ate by operating the double acting
lever, put the lever into the neutral
position immediately. If the relief
valve operates continuously, the oil
is overheated, leading to damage to
related parts.

DOUBLE ACTING LEVER
W h e n th e d e t e n t v a l v e is
in operation, unnecessary
load is applied to the engine.
Therefore, the engine power
decreases significantly, and
noise and vibration by open-
ing of the relief valve increase.
It is hard to start the engine
while the detent valve is in op-
eration. This is especially true
in winter and exhaust gas in-
creases even after the engine
is started.
IMPORTANT
Put the detent valve operating
lever into the neutral position
when the hydraulic implement
is not in use. If the detent
valve is kept in the operating
position for an extended pe-
riod of time, the relief valve is
kept open and the temperature
of the hydraulic fluid rises,
leading to damage of various
hydraulic parts, such as the
oil seals and O-rings.
