Hydraulic Steering Unit 060 Series

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.
