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 diagram 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 adapters with 11 mm [0.43 in] minimum bore.

The check valve in the LS line of OSPC LS and OSPD 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.
