Safety precautions

Warning
Unintended vehicle or machine movement hazard.
Unintended movement of the machine or mechanism may cause injury to the technican or bystanders. To prevent uintended movement, secure the machine or disable/disconnect the mechanism while servicing.
Warning
Flammable cleaning solvents
Some cleaning solvents are flammable. To eliminate the risk of fire, do not use cleaning solvents in an area where a source of ignition may be present.
Warning
Fluid under pressure
Escaping hydraulic fluid under pressure can have sufficient force to penetrate your skin causing serious injury and/or infection. This fluid may also be hot enough to cause burns. Use caution when dealing with hydraulic fluid under pressure. Relieve pressure in the system before removing hoses, fittings, gauges, or components. Never use your hand or any other body part to check for leaks in a pressurized line. Seek medical attention immediately if you are cut by hydraulic fluid.
Warning
Personal safety
Protect yourself from injury. Use proper safety equipment, including safety glasses at all times.
Warning
Product safety
Steering valves are safety components and therefore it is extremely important that the greatest care is taken when servicing these products. There is not much wear on a steering valve and therefore they normally outlast the application they are built into. Therefore the only recommended service work on steering valve is:
Changing seals and O-rings
•
Disassemble, clean and assemble if contaminated
•
Make hydraulic testing including valve setting
•

Disassembly

Fully disassembled EHi

To properly maintain and clean the now fully dismantled EHi Steering Valve, follow these steps.
This task illustrates the basic procedures for examining, cleaning, and maintaining EHi Steering Valve.
1. Check your own parts against those pictured below.
All parts except housing are illustrated
Cleaning:
2. Clean all parts carefully in Shellsol K or similar cleaner fluid.
Inspection and replacement:
3. Replace all O-rings. Check all parts carefully for damage.
In case any part appears damaged, or in case disassembly of any part was difficult or impossible, consider the EHi housing as damaged and replace the entire EHi valve.

Testing of EHi

This section describes minimum tests needed, when the EHi steering valve has been disassembled and reassembled.
Example of system setup: EHi5, Load Sensing Reaction to be used with OSPC LSR type steering unit:

Setup for testing

Use universal hydraulic work bench with pump capacity: 40 l/min [10.6 gal/min] and up to 280 bar [4061 PSI] pressure for relief valve setting and steering test.

Testing of EHi

EHi for LS steering units

The hydraulic oil must be with a viscosity of 21 cSt. at 50°C [122°F] and with maximum degree of contamination according to ISO 4406: 21/19/16.
Description for system setup, when priority valve is integrated in EHi and when EHi is configured to be used with LS type steering unit (as illustrated in system diagram above, EHi5):
1. Connect double rod cylinder to CL and CR ports of EHi.
2. Connect front T and EF port of EHi to tank of pump station.
3. Connect the front P port of EHi to P port from pump.
4. Connect the side P port of EHi to P port of LS steering unit.
5. LS1 of EHi:
a) When using pump station with fixed gear pump: Plug LS1 with steel plug
b) With LS pump in pump station: connect LS1 of EHi to LS of pump.
6. LS2 of EHi (is only present in EHi's with PVFC spool to be used for dynamic type steering units):
connect LS2 to LS port of OSP steering unit. LS dynamic flow will stream out of LS2 port of EHi, and must be able to pass on to tank.
7. Connect side T of EHi to T port of OSP.
8. Connect L and R of EHi to L and R of OSP.
9. Connect pressure gauges to all ports of EHi.
10. Connect voltage supply and signal input for the PVE.
T pressure should not exceed ~5 bar [73 PSI]. Maximum allowed T pressure is 25 bar [363 PSI]. Pump supply circuit must be adjusted not to exceed 280 bar [4061 PSI] P-T. In case the EHi has no RSV the OSP steering unit can be omitted from the tests.

In case the EHi has no RSV the OSP steering unit can be omitted from the tests. For EHi without integrated priority valve and with fixed gear pump in pump station, use external
priority valves:
For dynamic systems (when PVFC is present in EHi): Use Danfoss priority valve OLS 80 Code
•
152B8269, or other OLS 80 with same orifice and spring specification. Dynamic orifice: Ø1.0 mm. LS orifice: Ø1.2 mm. Spring: 7 bar [102 PSI].
For static systems (when PVFC is not present in EHi): Use Danfoss priority valve OLS 80 code
•
152B0263, or other OLS 80 with same spring specification: 10 bar [145 PSI].

With PVED CLS: The coil must be connected to and actuated by the PVED CLS.
•
With other PVE's: connect DC voltage and ground to the coil (12V or 24V depending on voltage
•
marking on the coil).
During the testing no disturbing vibrations, noise, or other irregularities must occur.
1. Start the pump, the pump flow is adjusted to approximately 25 l/min and pump pressure control
must be set to approximately 70 bar [1015 PSI].
2. Let the supplied oil flow through the steering valve for a few minutes. Then actuate the PVE a few
times in both directions to bleed of air from the EHi and the system. Observe that the steering cylinder is moving according to direction of input signal for PVE.
3. Operate the PVE to move the steering cylinder from end stroke to end stroke for at least 5 cycles.
Make sure pressure P-T, 70 bar [1015 PSI] can be achieved, when steering against end stroke. If this is not possible, the adjusting screw of the pilot relief valve (item 95 of exploded view) must be turned clockwise until P-T, 70 bar [1015 PSI] is achievable.

Pilot relief valve

Neutral positioning test

Cut off valve test

1. The pump flow is adjusted to approximately 25 l/min [6.6 gal/min] and pressure to max 280 bar [4061
PSI].
2. Steer the cylinder to an end stroke, keep input signal on PVE for full spool travel.
3. The pilot relief valve (item 95 of exploded view) is set according to specification:
Maximum steering pressure (P-T), bar, for the code in question. The setting pressure is the pressure on the P-port minus the T-port of EHi.
1. Apply input signal to the PVE to make a cylinder movement.
2. Remove input signal to the PVE, the steering valve must be able to go to neutral later than ~1 second:
cylinder movement must stop.
3. The EHi is proper in neutral position when the pressure drop (LS1-T of EHi) is no higher than 10 bar
[145 PSI] at pump flow 25 l/min [6.6 gal/min], and there must be no movement of the steering cylinder.
The cut off valve spool movement can be controlled by:
1. With electric power on coil and on PVE and with signal on PVE, the steering cylinder must move to
end stroke and maximum steering pressure must be build up.
2. Steer in opposite direction to observe cylinder movement.
3. While cylinder is moving, remove electric power to the coil (keep battery power and signal to PVE):
cylinder movement must stop and pressure (LS1-T of EHi) must drop to be no higher than 10 bar [145 PSI].

RSV valve test

If the EHi is equipped with an RSV valve, spool movement can be controlled by:

Steering tests
1. With electric power on coil and on PVE and with signal on PVE, the steering cylinder must move to
end stroke and maximum steering pressure must be build up.
2. Steer in opposite direction to observe cylinder movement. Apply input for slow movement of
cylinder, < 25% of max. signal.
3. Activate steering wheel to steer in opposite direction as movement of cylinder: cylinder movement
speed shall decrease/change to opposite direction dependent on steering wheel speed. Steering wheel torque must not exceed 10 N•m [88.5 lbf•in], when cylinder moves inside end strokes.

Check for external leakage

1. Remove the port connections, after testing the former items.
2. 2xP, CF, LS1, LS2, T-side, EF, L, R, CL and RL ports are to be plugged w. steel plugs.
3. Oil pressure of 20 bar [290 PSI] is supplied to the T-front port for approx. 3 minutes: No leakage must
be found in any assemblies.

Shock valves

If the EHi is equipped with shock valves, these are preset and locked in setting from factory. Solely no adjustments can be made on these valves.
