RD-5000 SERIES SPOOL ATTACHMENT OPTIONS
RD-5000 SERIES SPOOL OPTIONS
4 WAY 3 POSITION TANDEM CENTER
OPTION C
This spool option is used to control a double acting cylinder
or a reversible motor. In neutral both of the work ports are
blocked and oil goes through the open center passage to
the next spool of a multi-spool valve or the power beyond of
a single spool valve. This is the most popular spool option
and is used on most Prince standard valves.
4 WAY 3 POSITION CLOSED CENTER
This spool option is similar to spool option C above except
in neutral the open center passage is blocked. This function
is achieved by using spool option C with a closed center
conversion plug (Power beyond option D).
4 WAY 3 POSITION OPEN CENTER
MOTOR SPOOL OPTION E
This spool option can be used to control a bi-rotational
motor or a double acting cylinder. In neutral the work
ports are open to the return. This allows a cylinder
to drift or a motor to coast to a stop. In neutral the oil
goes through the open center passage to the next
spool of multi-spool valve or the power beyond of a
single spool valve.
4 WAY 4 POSITION OPEN CENTER
FLOAT SPOOL OPTION G
This option is the same as spool option C, 4 way 3 position
tandem center, with an added fourth “oat” position. In
neutral the work ports are blocked (this will hold up a
cylinder) and the oil goes through the open center passage
to the next spool or power beyond. In the oat position the
work ports are open to the return (this will allow a cylinder
to drift or “oat”) and the oil goes to next spool or power
beyond. The oat position is reached by pushing the spool
as far as it will go and Is held in place by a detent. This
option must be ordered with spool action option G.
3 POSITION SPRING CENTER TO
NEUTRAL OPTION A
This option has 3 positions and a spring that returns
the spool to neutral when the handle is released.
This option is considered standard on many Prince
valve models.
This option can be converted in the eld to 3 position
detent by ordering Kit 660150002. It can be converted
to friction detent by ordering Kit 660150003.
4 POSITION SPRING CENTER TO
NEUTRAL DETENT SPOOL ‘IN’ FOR
FLOAT POSITION OPTION G
This attachment Is used with spool option ‘G’. This
option provides for spring center to neutral from either
work position. It also provides a 4th position, oat
detent. The oat detent is reached by pushing the
spool in as far as it will go. In the oat position both
work ports are open to return. This allows a cylinder
to drift or “oat”.
This option is available only with spool option ‘G’ and
cannot be added to a valve in the eld.
FRICTION DETENT
OPTION C
This option provides for a detent in the neutral position
only. As the spool is manually moved away from the
neutral position it will be held in place by the friction of
the detent balls on the detent sleeve. Note: Because
the spool is held in place by friction only, excessive
vibration may cause spool to move when not in the
neutral detented position.
This option can be converted in the eld to spring
center by ordering Kit 660150001 and to 3 position
detent by ordering Kit 660150002.
3 WAY 3 POSITION OPEN CENTER
OPTION A
This spool option is used to control a single acting cylinder
or a unidirectional motor. In neutral the work port is blocked
and oil goes through the open center passage to the next
spool of a multi-spool valve or the power beyond of a single
spool valve. The “A” port is plugged for this option.
4 WAY 3 POSITION CLOSED CENTER
MOTOR SPOOL
This option is similar to spool option E except in
neutral the open center passage is blocked. This
function is achieved by using spool option E with
a closed center conversion plug (Power beyond
option D).
3 POSITION DETENT
OPTION B
This option provides three detented positions. The
spool will remain in any of the three positions in which
it is manually placed. No centering spring is provided.
Note: This option does not positively lock the spool
in place. Excessive vibration or shock loads may
effect operation.
This option can be converted in the eld to spring
center by ordering Kit 660150001. It can be converted
to friction detent by ordering Kit 660150003.
PRESSURE RELEASE DETENT,
DETENT SPOOL ‘OUT ONLY, SPRING
CENTER TO NEUTRAL OPTION E
This option provides a pressure release detent for
the spool ‘Out’ position. When the spool is manually
placed in the detent position oil is directed to the ‘B’
work port (the port away from the handle). When
the pressure in the ‘B’ port reaches a preset level
the detent will release and the spool will center. The
detent release pressure is factory set at 1200 psi.
This pressure is adjustable from 1000 to 2000 psi.
The detent release pressure is adjusted by turning the
adjusting screw clockwise to increase the pressure
and counter-clockwise to decrease the pressure. The
spool is spring centered to neutral from the spool ‘In’
position. This option can be used with spool options
A, C or E.
This option can not be added to a valve in the
eld.
PRESSURE RELEASE DETENT,
DETENT SPOOL ‘IN’ AND ‘OUT’
SPRING CENTER TO NEUTRAL
OPTION F
This option is similar to option ‘E’ above except the
pressure release detent function is on both the spool
‘In’ and ‘Out’ positions. This option is available on
RD-5100 valve and number 1 spool of RD-5200 and
RD-5300 valves.
This option can be used with spool options C or
E. This option can not be added to a valve in the
eld.
1 POSITION DETENT SPOOL ‘OUT’ SPRING CENTER
TO NEUTRAL
OPTION N
This option uses the same parts as option E above but is not pressure released.
The handle must be manually removed from the detent position. The detent holding
force is adjustable.
2 POSITION DETENT SPOOL ‘IN’ AND ‘OUT CENTER
CENTER TO NEUTRAL
OPTION P
This option uses the same parts as option F above but is not pressure released.
The handle must be manually removed from the detent position. The detent holding
force is adjustable.
