Function of the incorporated valve
Inlet safety valve: Limits maximum pressure drop across the PSU to protect the steering circuit.
Cylinder port shock valve: Protects hoses against pressure surge created by ground forces on the cylinder axle.
Anti- cavitation valve: Protects steering circuit against vacuum (cavitation) conditions.
Inlet check valve: Prevents oil from returning through the PSU when pressure on the cylinder side is greater than the inlet side. It prevents steering wheel kick.
Internal check valve: Converts the PSU to a hand operated pump for limited manual steering.

Hydraulic steering unit is widely used in the steering control system

 such as the steering system of many kinds of industrial and agricultural

mobile machinery forklift,loader,roadroller,tractor,comebine harvester, etc.
