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 neutral
position to block the hydraulic fluid
when it is pushed/pulled and then
released.
Therefore, this type of double act-
ing 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 act-
ing valve lever, it keeps its posi-
tion after it is pulled or pushed to
a certain position. Therefore, it is
not necessary to hold the lever to
a certain position which is suitable
for an implement with a long oper-
ating time, such as the hydraulic
motor.
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.
When the detent valve 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.
