hydraulic steering unit for Fiat tractor 88-60 orbitrol power 101S 100CC open center non-reaction good quality OSPC 100ON
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. 101s 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.

Applications:
We offer hydrostatic steering systems for small and medium-sized vehicles, typically tractors, harvesters, forklift trucks, and smaller contractors’ machines.
Its role is to increase the power steering wheel steering transmission to the transmission mechanism and change the direction of transmission.
Widely used in , shipbuilding machinery, garden machinery, road maintenance machinery, forestry machinery, construction machinery and mining machinery and other low-speed heavy vehicles.
With it, the driver can achieve greater steering force control with a smaller steering force, and the performance is safe and reliable, the operation is light and flexible.
