2-way cartridge valves with spool position monitoring | Directional valves 3/72
RE 21015, edition: 2014-11, Bosch Rexroth AG
General Information
Inductive position switch
Contactless position switches with integrated switching
amplifiers switch shortly before the spool position to be
monitored is reached. The spool position reached is dis-
played by a binary signal.
Advantages of the position switches:
▶ Short-circuit-proof
▶ Direct monitoring of the spool position at the control
spool
▶ Long life cycle
▶ High reliability due to no use of dynamic seals
▶ Reaction time of the switch upon operation approx.
15ms.
Notes:
Valves with inductive position switches and proximity
sensors in safety-relevant controls may only be assem-
bled and commissioned by hydraulically and electrically
trained experts. Service work requires special tools and
equipment. This work may only be performed by autho-
rized specialists or in the factory!
Improper work at safety equipment leads to a risk of
personal injury and damage to property!
▶ The valve components are coordinated with each
other in the production plant and adjusted during
assembly. They must not be interchanged. In case of
valve or position switch defects, the entire valve
must be exchanged!
▶ The factory setting of the position switch must not
be changed. The position switch may only be set by
BoschRexroth.
▶ The position switch must be automatically moni-
tored by the machine control to prevent initiation of
a new machine cycle even if the safety is called up
on the position switch.

4/72 Directional valves | 2-way cartridge valves with spool position monitoring
Bosch Rexroth AG, RE 21015, edition: 2014-11
Components of the system
Cartridge element (seat valve design with damping noses)
Cartridge valves are hydraulically controlled seat or spool
valves with two working ports A and B, as well as a control
port X or two control ports X and Z for versions with differ-
ential spool. Y is usually the leakage oil connection. The
valves are available in the sizes 16, 25, 32, 40, 50, 63, 80,
100, 125 and 160.
The main criteria for determining the size are the flow to
be controlled, as well as the flow resistances of the car-
tridge valves and their area ratios.
Control cover
The control cover (2) closes the bore of the installation
elements. It also acts as a link between the cartridge valve
and the pilot control valve.
Pilot control valve
With control covers for setting up a directional spool valve
(3) or seat valve (4), the positions of the ports are
arranged according to ISO4401 and DIN 24340
The cartridge element (1) and the control cover (2) form a
functional unit. It is calibrated in the factory and must not
be dismantled or combined with other foreign matter.
The mounted position switch (5) monitors the closed
spool position.

2-way cartridge valves with spool position monitoring | Directional valves 5/72
RE 21015, edition: 2014-11, Bosch Rexroth AG
Function, section, symbol
2-way cartridge valves are elements that have been
designed for a compact block design. The power section
with ports A and B is installed into the manifold in a receiv-
ing hole standardized according to ISO 7368 and closed
with a cover. In most cases, the cover is simultaneously the
connection from the control side of the power section to
the pilot control valves. By controlling with the relevant
pilot control valves, the power section can take over the
pressure, directional and throttle function or a combina-
tion of these functions. Particularly economical solutions
are achieved by adapting the nominal size to the different
levels of flow of the individual ways of an actuator. One
extremely economical method is to transfer multiple func-
tions on the power section of an element.
2-way cartridge valves consist mainly of a control cover (1)
and an installation kit (2). The control cover contains the
control bores and stroke limitation, hydraulically controlled
directional seat valve or a shuttle valve depending on the
overall function required. Electrically operated directional
spool valves or directional seat valves can also be mounted
on the control cover. The installation kit consists of a
socket (3), ring (4) (only up to size 32), valve poppet (5),
optionally with damping nose (6) or without damping nose
(7), and closing spring (8).
2-way cartridge valves work depending on the pressure.
This results in three pressurized areas A
1
, A
2
, A
3
, which are
important for the function. The area on the valve seat A
1
is
regarded as 100%. The annulus area A
2
resulting from the
gradation is 7% or 50% of the area A
1
depending on the
version. The area ratio A
1
: A
2
is therefore either 14.3 : 1 or
2 : 1. Area A
3
is equal to the sum of areas A
1
+ A
2
. Due to
the different area ratios A
1
: A
2
and the resulting different
annulus areas (A
2
) area A
3
is 107% or 150% of the area
regarded as 100% A
1
on the seat.

The following applies:
Area A
1
and A
2
act in the opening direction. Area A
3
and
the springs act in the closing direction. The direction of
action of the resulting force from opening and closing
forces determines the spool position of the 2-way car-
tridge valve.
The 2-way cartridge valves can be flown through from A to
B or from B to A. When the area A
3
is pressurized by
removing pilot oil from channel B or external pilot oil
supply, channel A is blocked leak-tight.
For the installation bore and connection dimensions see
data sheet 21010.

1)
The cleanliness classes stated for the components need to be
maintained in hydraulic systems. Effective filtration prevents
faults and at the same time increases the life cycle of the com-
ponents.
For the selection of the filters see www.boschrexroth.com/filter.

Important information on hydraulic fluids:
▶ For more information and data about the use of other hydraulic
fluids, refer to data sheets above or contact us!
▶ There may be limitations regarding the technical valve data (tem-
perature, pressure range, life cycle, maintenance intervals, etc.)!
▶ Flame-resistant – containing water:
– Maximum pressure differential per control edge 50bar
– Pressure pre-loading at the tank port > 20% of the pressure
differential, otherwise increased cavitation
– Life cycle as compared to operation with mineral oil HL, HLP
50 to 100%
