Characters:
101s ON/OR for hydraulic systems where oil is supplied by a fixed-displacement pump. The range is wide and flexible, characterised by: • Low steering torque, 0.5 Nm to 1.8 Nm in normal steering situations • Low noise level and wide control range • One or several built-in valve functions: pressure relief, shock, suction, and/or nonreturn in pump connection • Port threads as required, to DIN, ISO, SAE or JIS standards.
101s is available in versions “Open Center Reaction” or “Open Center Non Reaction” (OR or ON) and with displacements from 40 to 500 cm3 /rev. OSPC is also available in a “Closed Center Non Reaction” (CN) type. CN steering units are for constant-pressure systems with variable pump flow. In neutral position, the CN unit shuts off oil flow between pump and tank. CN units are available with displacements from 50 to 400 cm3 /rev.
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.
