060 integral series power steering units
060 series PSU incorporated the inlet check valve, safety valve, internal check valve, cylinder port shock valve and anti-cavitation valve. The design is more compact and convenient.
Incorporated five valves into the PSU, So it is more compact and convenient

Special casting design for low pressure drop.
3 basic systems-open center, closed center and load sensing
Displacement: 50~500 ml/r
Main specification data
Max. System pressure --------16MPa
Max. Back pressure -----------2.1MPa
Max. System operating temperature--------93º C
Recommended oil filtration--------ISO 19/16
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.
