Versions
Load sensing
In load sensing steering systems both the steering system and the working hydraulics
can be supplied with oil from the same pump, using a load sensing pump, also delivers
the potential for energy saving.
Load sensing steering units have an extra connection for load sensing (LS), so that a load
pressure signal can be directed via the steering unit to a Sauer-Danfoss priority valve
and/or an LS pump. The load sensing signal controls the oil flow from the priority valve
(and/or the LS pump) to the steering unit. The LS connection is open to tank when the
steering unit is in the neutral position.
Load sensing static
Load sensing static steering units require load sensing static priority valves and/or load
sensing static variable displacement pumps. Load sensing static steering systems have
no oil flow in the LS connection when the steering unit is in neutral position.
Load sensing dynamic
Load sensing dynamic steering units require load sensing dynamic priority valves and/
or load sensing dynamic variable displacement pumps. Load sensing dynamic steering
systems have a constant oil flow in the LS connection in the direction of the steering unit
even when the steering unit is in neutral position.
Reaction
With reaction steering units any external forces acting on the steered wheels result in
a corresponding movement of the steering wheel when the driver is not steering the
vehicle.
Non-reaction
With non-reaction steering units there is no corresponding movement of the steering
wheel when the driver is not steering the vehicle

Version
OSPD LS: Steering unit load sensing
dynamic with 2 rotary meters and with
integrated valve functions
The OSPD has 2 rotary meters (gear
wheel sets). Should the pump supply be
lost, only one rotary meter is active for
emergency steering. In normal steering
situations both rotary meters are active.
OSPQ LS: Steering unit load sensing
dynamic with flow amplification and
with integrated valve functions
The OSPQ has incorporated amplification
valve. Should pump supply fail or the
steering wheel speed be less than
approximate 10 rev/min only the rotary
meter determines the displacement. In
normal steering situations or at higher
steering wheel speed, oil is also led to
the steering cylinder via the built in
amplification valve.

Technical Data
Valve functions in OSPC, OSPF, OSPD, OSPQ and OSPL LS steering units
Pilot pressure relief valve; (P - T, Qp) characteristic
The pilot pressure relief valve protects the steering unit against excessive pressure.
The pilot pressure relief valve in the OSPC LS, OSPF LS, OSPD LS, OSPQ LS and OSPL LS
steering unit together with the priority valve limit the maximum steering pressure P-T.
The pilot pressure relief valve is set at an oil flow to the priority valve of 25 l/min
[6.60 US gal/min].
For OSPC, OSPD, OSPQ and OSPL load sensing dynamic steering units, the setting values
are valid at a dynamic flow of 0.6 l/min [0.16 US gal/min].
For OSPF load sensing dynamic steering units, the setting values are valid at a dynamic
flow of 1.1 l/min [0.29 US gal/min].
Setting tolerance:
</= 170 bar: rated value +5 bar [72.5 psi].
> 170 bar: rated value +10 bar [145 psi].

Shock valves
The shock valves protect the steering unit and reduce external forces on the steering
cylinder by limiting the pressure difference from L to T and from R to T.
The shock valves are set at 3 l/min [0.792 US gal/min]
At higher flow pressure peaks may occur.
The shock valves are of the direct acting type, so they react very quickly.
Setting tolerance: rated value +20 bar [290 psi].

Technical Data
Suction Valves
The suction valves allow oil suction to avoid cavitation in the steering cylinder. To
provide correct suction, a back pressure valve must be fitted in the tank line from the
steering unit.
Generally Sauer-Danfoss recommend a back pressure of 2 bar [29 psi], but on vehicles
with strong self straightening tendencies and on articulated steered vehicles, we
recommend 5-10 bar [72.5 - 145 psi]. For further advice, please contact the SauerDanfoss Sales Organisation.
Note: A connection which incorporates a check valve must be established to allow oil
flow to by-pass the back pressure valve (and filter) from the tank to steering unit. See
diagramme examples in sub catalogue “General Steering Components” page 37 - 39.

Check valves
The check valve in the P connection of the steering unit protects the driver against
steering wheel jerks. The check valve prevents oil from flowing backwards into the pump
line when steering against a high pressure on the cylinder side. The pressure drop across
the check valve is indicated on the following graph, which assumes the use of port
adaptors with 11 mm [0.43 in] minimum bore.

The check valve in the LS line of OSPC LS, OSPD LS and OSPQ LS dynamic steering units
also protects the driver against steering wheel jerks. The check valve prevents oil from
flowing backwards into the LS line to the priority valve when steering against a high
pressure on the cylinder side.
In OSPF LS oil cannot flow backwards into the LS line, look in sub catalogue: “General
Steering Components “ page 26.

Shock valves
The shock valves protect the valve block and steering unit and limit maximum external
forces on the steering cylinder. The shock valves in the valve block limit the maximum
pressure drop from L to T and from R to T.
The shock valves are set at 10 l/min. [2.64 US gal/min].
The shock valves are of the direct acting type, so they react very quickly.
Setting tolerance: rated value +/- 10 bar [145 psi] , ex. 240 [3480 psi] +/- 10 bar [145 psi].
Suction valves
The suction valves ensure oil suction to avoid cavitations in the steering cylinder. To
provide correct suction, a back pressure valve must be fitted in the tank line from the
steering unit.
The capacity of the suction valves can be increased by building in a back pressure in the
valve block.

Check valve
The check valve protects the driver against steering wheel jerks. The check valve
prevents oil from flowing backwards into the pump line when steering against a high
pressure on the cylinder side.
The check valve is built into the P connection of the valve block.

Priority Valves OLSA and OLS
Versions
Sauer-Danfoss priority valves are used in steering systems with load sensing
steering units. In such systems steering always has first priority
Load sensing static priority valves
Load sensing static steering units require load sensing static priority valves. Load sensing
static steering systems have no oil flow in the LS connection when the steering unit is in
neutral position.
Load sensing dynamic priority valves
Load sensing dynamic steering units require load sensing dynamic priority valves. Load
sensing dynamic steering systems have a constant oil flow in the LS connection from the
priority valve to the steering unit even when the steering unit is in neutral position.
Ports:
P = pump,
CF = controlled flow (priority oil flow),
EF = excess flow,
L = left,
R = right,
T = tank,
LS = load sensing,
PP = pilot pressure
OLSA 40/80 The OLSA 40 and OLSA 80 “flange on” priority valves are used in load sensing steering

The priority valve OLSP 80 is to be used in connection with e.g. Sauer-Danfoss gear
pumps type SNP and steering units type OSPB LS, OSPC LS, OSPF LS, OSPD LS and OSPQ
LS in load sensing steering systems, where maximum oil flow doesn’t exceed 80 l/min
[21.7 USgal/min].
OLSP 80 priority valves are to be flanged on gear pumps with outlet ports square flange
type 35 (35 mm pitch diameter of 4x M6 bolt holes for fixing the priority valve on pump).

The priority valve OLS 320 is to be used in connection with large pumps and steering
units type OSPB LS, OSPC LS, OSPF LS, OSPD LS, OSPQ LS and OSPL LS or with EHPS
steering valve in load sensing steering systems, where maximum oil flow doesn’t exceed
320 l/min [84.5 USgal/min].

EHPS steering valve has build in priority
valve, but for max. pump flow 120 l/
min [31.7 USgal/min] In systems with
EHPS and pump flow between 120 l/
min [31.7 USgal/min] and 320 l/min [84.5
USgal/min] a combination of EHPS and
OLS 320 gives a good compact solution
to reduce hosing and installation cost
compared with stand alone components.
For further details of this OLS 320: look in
EHPS catalogue 520L0521.

System Sizing
The steering system pump is sized so that satisfactory performance is achieved for both
steering and working hydraulics - even at idle.
Before selecting a priority valve, consider
• the type of steering unit (LS static, LS dynamic or OSPF LS dynamic)
• the displacement of the steering unit
• the pump flow
• the application’s requirement for energy optimization, initial steering response time
and stability, as these all govern the selection for control spring pressure
• whether the priority valve should have internal PP (Pilot Pressure) or external
PP-connection depends on the pressure drop in the pump line between the priority
valve’s CF-port (Controlled Flow) and the steering unit’s P-port. With normal hose and
tube dimensions and less than 5 m distance between priority valve and steering unit,
the immediate choice is normally a priority valve with internal PP.
The following survey lists the code numbers of the priority valves that are the most
frequently used in connection with the above Sauer-Danfoss steering unit types. All
priority valves in the code number tables, except OLS 160 static, have internal PP
connection. OLS 160 static in the code number table all have external PP connection.

Pressure Drop in
Priority Valves
Pressure drop in priority valves
This data comes from measurements on a representative sample of priority valves
from production. Oil with viscosity of 21 mm2/s at 50 °C [102 SUS at 122 °F] was used
during measuring. Measurement made when pressure on the LS connection is zero
(steering unit in neutral position). The minimum curves apply when the pressure on the
EF connection is higher than the actual control spring pressure. The curves for control
spring pressure of 4 , 7, 10 or 12 bar [58, 101, 145 or 174 psi] apply when pressure on the
EF connection is zero.

OLS 160, pilot pressure relief valve (P - T, Qp) characteristic
OLS 160 with pilot pressure relief valve is used in connection with Sauer-Danfoss
steering units without pilot pressure relief valve, normally steering unit type OSPL.
The pilot pressure relief valve protects the steering unit against excessive pressure. The
pilot pressure relief valve in OLS 160 operates with the priority valve spool in the OLS 160
to limit the maximum steering pressure P-T measured across the steering unit ports.
The pilot pressure relief valve is set when an oil flow of 80 l/min[21 US gal/min] is
supplied to OLS 160.
Setting tolerance:

Technical Data
Valve functions in the flow amplifiers
The datas below come from measurements on a representative sample of flow amplifiers
from production. Oil with viscosity of 21 mm2/s [102 SUS] at 50 °C [122 °C] was used
during measuring.
Priority valve
The priority valve is used in load sensing systems where the same pump supplies oil to
both the steering system and working hydraulics. The steering system always has first
priority. Measurements were made when the pressure on the LS connection is zero.
(steering unit is in neutral position). The minimum curves apply when the pressure
on the EF connection is higher than the actual control spring pressure. The curves
for control spring pressure of 7 bar [101.5 psi] apply when the pressure on the EF
connection is zero

Shock valves
The shock valves protect the flow amplifier against shock from external forces on the
steering cylinders. The shock valves in OSQA and OSQB limit the maximum pressure
drop from CL to HT and from CR to HT. The shock valves are set at 10 l/min [2.64 US gal/
min].
Setting tolerance: rated value +20 bar [290 psi].
Suction valves
The suction valves ensure oil suction on the side of the steering cylinder pistons where
in unfavorable conditions cavitation might occur. The capacity of the suction valves is
increased in OSQB by the built-in back pressure valve.

Technical Data
Priority valve OLSQ for emergency circuit in OSQB/OLSQ
When under normal steering conditions the stand-by pressure in the main circuit
(minimum 7 bar [101.5 psi] priority valve spring in OSQ) overrules the spring pressure
in OLSQ (4 bar [58 psi] spring), OLSQ’s priority valve will pass oil from the emergency
steering pump across OLSQ’s P-connection to the flow amplifier’s HT tank connection.
If the oil supply from the main pump should fail, the stand-by pressure of OSQ’s priority
valve in the main pump circuit disappears and relocates the spool in OLSQ to enable the
oil from the emergency steering pump to enter the pump circuit in the OSQ.
The curve shows the pressure drop from OLSQ’s P-connection to OSQ’s HT-connection
with an active main pump and neutral positioned steering. The curve solely applies to
OSQs without any back pressure valve in the tank line.
