Technical Information
OSPE Steering Valve
General Information
General steering valve type OSPE
On tractors, combine harvesters, maize harvesters and other simulate vehicles there is often a need forelectrically actuated steering to make automatic GPS controlled steering possible. Also manual steeringwith variable ratio is an often wanted feature to improve productivity and driver comfort.
For this purpose Danfoss has developed a combined steering unit and electrohydraulic steering valve
named OSPE: OSP for normal manual steering wheel activated steering and E for electrohydraulicsteering activated by electrical input signal either from GPS or vehicle controller or from steering wheel
sensor (Danfoss type SASA) for variable steering ratio. In variable steering mode, the electrohydraulicvalve part adds flow to the metered out flow from the steering unit part of the OSPE.
OSPE has build in safety function in form of cut off valve, which makes unintended steering from Electro
hydraulic valve part impossible. The OSPE is the right steering element first of all to build up steeringsystem with very high safety level and so to be able to fulfill legislation demands such as those in EU
Machinery Directive 2006/42/EC.
OSPE is offered with the PVED-CLS steering valve controller. PVED-CLS offers integrated, flexible
software-based electrohydraulic steering functionality which can be tailored to any off-road vehicle typeby software parameterization. The PVED-CLS also works as a certified Safety Controller. For further details
about PVED-CLS, see OSPE with PVED-CLS Steering Valve Controller Data Sheet, AI152986484866.
In cases where space do not allow room enough for OSPE, an ordinary OSP non-reaction steering unit
combined the EH-Electrohydraulic In-Line steering valve is an alternative. EH valves are offered with thesame safety functions as OSPE. Please contact Danfoss sales organization.

OSPE Steering Valve
Versions
OSPEC LS/LSRM with PVED-CLS
This version is preferred for front wheel steered vehicles, like tractors, where self-alignment steering
effect is desired. Reaction type steering resembles a car where the direction of travel will continue
straight ahead when ever the steering wheel is not touched. The reaction concept in any OSPE steering
units is based on Danfoss RM technology. The reaction effort is selectable by help of the solenoid valve
for activating EH steering:• Road mode: When EH steering is powered off, then OSPE behaves the same as a Reaction unit•

Field mode: When EH steering is powered on, then OSPE behaves the same as a Non-reaction unit

Neutral spring package for spool/sleeve

When the engine is turned off, the priority valve spool (15) is pushed to the left by the spring (16).
The passage to the EF port is blocked and the passage to CF to the OSP spool/sleeve set (3) and to the EH
directional valve spool (8) is open.
When the engine is on and the steering unit OSP and EH is in neutral position, the CF pressure will rise tomatch the spring force in the priority valve, and the priority valve spool (15) will move to the right andthe oil will pass from the pump across the integrated priority valve spool (15) and out through the EF
port.
The priority valve is a “dynamic” type, meaning that a flow passes from CF through the Dynamic orifice(17) (integrated in spool 15) and into the LS line through the LS orifice (19), LS check valve (20), the PVFC
valve (21) and into the spool/sleeve set (3). In neutral position this dynamic oil flow passes on to the tank.
When the steering unit is in neutral position and control valve (12) is deactivated, then the mode
select/EH cut off valve (7) makes connection through the Reaction circuit, Lr and Rr. So if the steering
wheel is untouched and a delta P is generated in the steering cylinder, oil will pass from L to R or R to L
through the spool/sleeve set (3) and gear set (5) and the steering wheel will rotate until it is grabbed ordelta P disappears. Only the force of the neutral spring package (22) has to be overcome to stop therotation of the steering wheel and therefore stop the cylinder movement. The mode select/EH cut off
valve (7) makes unintended EH steering impossible, if e.g. a false input signal comes to the PVE control
unit (9), when the control valve (12) is deactivated, because L and R connections from EH directional valve
spool (8) are blocked in (7).
If the control valve (12) is activated, then the mode select/EH cut off valve (7) blocks connection throughthe Reaction circuit. In this position there will be no reaction behavior even if there is build up delta P on
the steering cylinder from forces on the steered wheels. So the steering unit behaves as a Non reaction
OSP. In that situation (If the control valve (12) is activated) EH steering is possible.

Neutral spring package for spool/sleeve

When steering with the steering wheel to the right, the spool of the spool/sleeve set (3) will rotate
relative to the sleeve. So LS line will be connected to R-side. LS pressure will raise accordingly to steeringpressure required and priority valve spool (15) will be pressed to the left and oil will stream through theinternal CF side of the priority valve and on to the spool/sleeve set (3) through the gear set (5) and out
through the R connection. In parallel the L side is opened through the spool/sleeve set (3) to tank (T).
When steering up against cylinder end stop, pressure will raise in LS line according to setting of pilotpressure control valve (18). Check valve (20) avoids oil to stream backwards from servo side (R in thiscase) and over valve (18) to tank. So the valve (18) shall only open for the dynamic flow generated in the
dynamic orifice (17) of priority valve part, independent if steering is done by the steering wheel (OSPpart) or by the EH valve.

Before it is possible to steer with the EH part of the OSPE, it is needed to power the control valve formode select (12) for field mode. When this valve is powered, the pilot supply (12 bar) is lead from thepilot reduction valve (13) through the control valve (12) to the EH cut off valve (7). So the valve (7) makes
connection from EH directional valve (8) to the cylinder ports, L and R, and (7) also leads pilot supply tothe solenoid valve bridge (11) of the PVED CLS control unit (9) In the same shift, the valve (7) interrupts
the reaction circuit, Lr and Rr, from the spool/sleeve set (3) to the cylinder ports, and the unit acts as a
non-reaction OSP in this mode.
When an input signal is transmitted to the electrical connector of the PVE (9), in this example signal tosteer to the right, the solenoid valve bridge (11) is activated and the EH directional valve spool (8) is
moved to the right. So LS in the spool (8) will sense the needed steering pressure, and this is transmitted
to the PVFC valve /LS resolver (21). So the valve (21) makes restrictions in the dynamic LS flow fromdynamic orifice (17) of priority valve, and the LS pressure in the priority valve spool (15) will match the LSpressure required from the EH directional valve spool (8). Accordingly the position of the priority valve
spool (15) will change to match the flow and pressure demand for EH-steering.
In case the “watch dog” part of the PVED CLS registers an unintended steering movement e.g. due to afalse input signal to the PVE, the electrical power to the control valve for mode select (12) will beswitched off.
So valve 12 will dump pilot pressure to tank, mode select and EH cut off valve (7) will change position sothat connection from EH directional valve spool (8) to cylinder ports will be blocked. Furthermore it will
not be possible to activate the solenoid valve bridge (11) and the PVE will go into/stay in neutral position.
In this way a true safe state is established.
The non-reaction circuit from the OSP part is always connected to L and R cylinder ports independent of
position of mode select valve (7), and so OSP steering is always possible.
PVES and PVED-CLS, electrical actuation
The philosophy of Danfoss electrohydraulic actuation, type PVE, is integration of electronics, sensors andactuators into a single unit that interfaces directly to the OSPE steering valve body.

Technical Information
OSPE Steering Valve
Function
Closed loop control
All the proportional actuators feature an integrated feedback transducer that measures spool movement
in relation to the input signal, and by means of a solenoid valve bridge, controls the direction, velocity
and position of the main spool of the valve. The integrated electronics compensate for flow forces on thespool, internal leakage, changes in oil viscosity, pilot pressure, etc. This results in lower hysteresis andbetter resolution. Furthermore the electronics enable built in safety like fault monitoring, directional
indication and LED light indication.
Closed loop control schematic

Principle
In principle the input signal (set-point signal) determines the level of pilot pressure which moves themain spool. The position of the directional spool is sensed in the LVDT transducer which generates anelectric feed-back signal register by the electronics. The variation between the set-point signal and feedback signal actuates the solenoid valves. The solenoid valves are actuated so that hydraulic pilot pressure
drives the directional spool into the correct position.
Inductive transducer, LVDT(Linear Variable Differential Transformer). When the directional spool is moved, a voltage is induced
proportional to the spool position. The use of LVDT gives contact-free monitoring of the directional spool
position. This means an extra-long working life and no limitation as regards the type of hydraulic fluid
used. In addition, LVDT gives precise position signal of high resolution.
Integrated pulse width modulation
Positioning of the directional spool in PVES is based on the pulse width modulation principle. As soon as
the directional spool reaches the required position, modulation stops and the spool is locked in position.

Dimensioning
Dimensioning steering system with OSPE steering valve
The cylinder flow is determined from steering cylinder volume, number of revolutions on steering wheelfrom lock to lock and steering speed. Dimension of steering cylinder(s) can be based on formulas in“General, steering components” page 29-31.
Symbols:V (l)steering cylinder volumei (rev)number of steering wheel revolutions from lock to lockVvc (cm3/rev.)

Swd (m)steering wheel diameter

Vvs (cm3/rev)

displacement, steering unit

PQ (l/min)pilot flow

Qpm (l/min)pump flow, minimum

Example:Cylinder volume: V = 1.85 l [0.49 US gal]
Required number of steering wheel revolutions from lock to lock:i = 4 – 5 revolutions
The required steering system displacement for steering cylinder is calculated from
Vvc = V/i = (1.85*1000)/5 = 370 cm3/rev [22.58 in3/rev](1.85*1000)/4 = 463 cm3/rev [28.25 in3/rev]
In this example we chose Vvc = 400 cm3/rev [24.4 in3/rev]
The nominal cylinder flow at 100 rpm speed on steering wheel.
CQ = 400 * 100/1000 (cm3/l) = 40 l/min [10.57 US gal/min]
In this case we try to use an “D” type steering unit to avoid emergency steering pump.
The “small” gear set, which is the only hydraulically active gear set in emergency steering mode isdetermined by the demand for emergency steering pressure.
Emergency steering pressure, Pems, is calculated to be maximum Pems = 40 bar [580 psi]
Maximum allowable steering torque Tems based on steering wheel rim force Fe=350 N and steering
wheel diameter Swd = 0.381 m
Tems = Fe * Swd/2 = 350 * 0.381/2 = 66.7 Nm [580 lbf•in]
Emergency steering unit displacement can be chosen/calculated from the table lowest in “General,steering components” section. The nearest displacement Vvs generating
minimum 40 bar [580 psi]at Tws = 66.7 N•m [580 lbf•in]
Vvs maximum = 80 cm3/rev [4.88 in3/rev]
So the closest combination on gear sets for this OSPED type will be: 80/395. So the numbers of steering
wheel revolutions from lock to lock will be.
i = V/Vvc = 1850/395 = 4.7 turns lock to lock.

Pressure drop P-EF for Danfoss OSPE valve
This data comes from measurements on a representative sample of OSPE valves from production. Oilwith viscosity of 21 mm2/s at 50 °C was used during measuring. Measurement is made when the pressure
on the LS connection is zero. The minimum curve applies when the pressure on the EF connection ishigher than the actual control spring pressure.
The curve for control spring pressure of 7 bar [100 psi] and 10 bar [145 psi] applies when pressure on the
EF port is zero.

The pump, the OSPE priority valve part and the working hydraulics must be protected by a separatepressure relief valve. The PVED-CLS monitors input from the GPS, MMI, joy stick, mini wheel, steering
angle sensor (SASA) and signal from steering cylinder sensor. In case of unintended movement from thecylinder sensor, the PVED-CLS will remove power to the control valve for mode select/pilot dump, and in
this way electrohydraulic actuation of steering cylinder is made impossible. The system turns into true
safe state.

Technical Information
OSPE Steering Valve
System Safety
Emergency steering
The steering unit part of the OSPE acts like any other OSP steering units in case of no pump supply.
In such case the gear wheel set acts as a hand driven pump, and so muscular power will be converted
from input torque and rotation on the steering wheel to hydraulic power in the form of pressure and flowout of the cylinder port to which side the steering is done. See Dimensioning steering system with OSPE
steering valve on page 27 in this catalog and page 28 in “General, steering components” for calculating
manual/emergency steering.
Please see promotional brochure AV152886482496 for further information.
OSPE and system safety PVES
Fault monitoring
A fault monitoring system is provided in all PVES modules. The system is available as passive fault
monitoring type, which provides a warning signal only.
• Passive fault monitoring systems are triggered by three main events:
1. Input signal monitoring
The PVES input signal voltage is continuously monitored. The permissible range is between 15%
and 85% of the supply voltage. Outside this range the section will switch into an active error state.
2. Transducer supervision
If one of the wires to the LVDT sensor is broken or short-circuited, the section will switch into an
active error state.
3. Supervision of the closed loop
The actual position must always correspond to the demanded position (input signal). If the actual
spool position is further than the demanded spool position (>12%, ), the system detects an error
and will switch into an active error state. On the other hand, a situation where the actual position iscloser to neutral than that demanded will not cause an error state. This situation is considered “incontrol”.
When an active error state occurs, the fault monitoring logic will be triggered:

•

A delay of 250 ms before anything happens.
The solenoid valve bridge will not be disabled but still control the main spool position.
An alarm signal is sent out through the appropriate pin connection, no. 3.
This state is not memorized. When the erroneous state disappears, the alarm signal will turn topassive again. However, the signal will always be active for a minimum of 100 ms when triggered.

To prevent the electronics from going into an undefined state, a general supervision of the power supply
and the internal clock frequency is made. This function applies to PVES and will not activate fault
monitoring:
1. High supply voltage
The solenoid valves are disabled when the supply voltage exceeds 36 V, and the main spool will
return/stay in neutral.
2. Low supply voltage:
The solenoid valves are disabled when the supply voltage falls below 8.5 V, and the main spool will
return/stay in neutral.
3. Internal clock
The solenoid valves are disabled when the internal clock frequency fails, and the main spool will
return/stay in neutral.

Safety considerations
On-road operation

W Warning
The PVES or PVED-CLS shall be de-energized while driving on-road. It is the OEMs responsibility toestablish the necessary means to inform and de-energize the PVE from the cabin when driving on publicroads.
The Danfoss range of PVE actuators are single string designs with limited on board fault monitoring.
Danfoss strongly recommends application of vehicle specific safety monitoring systems that will detect
non-conforming steering and effectively disable electrohydraulic actuators or issue appropriate warnings
as the case may be. A minimum safety system should include a manual power switch to electrical power
off electrohydraulic actuators while driving on public roads.

W Warning
OSPEF w. displacement < 250 cc/rev. and integrated priority valve not to be used!
Using a combination of OSPEF with displacement < 250 cc/rev. and integrated priority may cause
oscillations in steering system. Therefore, do not specify such combinations. The OSPEC is recommended
for use when displacement is smaller than 250 cc and if integrated priority valve is needed.
Specify the OSPE in the OSPE Design Center Configure with MMC format shown in OSPE master model
code (MMC) breakdown on page 38.
