reassembled.

OSPEDC LSRM with integrated priority valve:

PVE

Electronics

OSP

P301 171

Set up for testing

A universal hydraulic work bench is required for this setup. The work bench must support the following
pump capacity.

•

25 l/min and up to 210 bar pressure for relief valve setting and steering test

•

3 l/min and up to 280 bar pressure for shock valve setting

The hydraulic oil must have a viscosity of 21 cSt. at 50°C with a maximum degree of contamination
according to ISO 4406: 21/19/16.

Set up OSPE with integrated priority valve

1. Connect double rod cylinder to L and R ports of OSPE.
2. Connect pressure gauges to all ports of OSPE.
3. Connect steering column and steering wheel to the input shaft of the OSPE.
