Product description 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. Features Incorporated five valves into the psu, so it is more compact and convenient Low hydraulic noise 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 Input torque--------------------1.7~2.5nm Max. System operating temperature--------93 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.
