Flow Amplifier
The FA(M) flow amplifier is used in large vehicle typically very large fork lift trucks, loaders, dumpers. The flow amplifier amplifies the oil flow from the power steering unit cylinder ports L or R by an amplification factor. The amplified oil flow is directed from the flow amplifier ports CL or CR to the steering cylinder. The amplified flow is proportional to the rate of steering wheel rotation
Features
- High steering capacity
- Low pressure drop at high flow
- Built in valve: a direction valve, an amplification stage, a priority valve, a pilot pressure relief valve, a back pressure valve, shock and suction valves
Specification
- Max. steering pressure : 210bar(20.6MPa)
- Rated Flow : FAM : 160L/min, FA : 400L/min
- Amplification factors: 4, 5, 8, 10
- Total displacement of steering system :
- FAM: 480~1600cc/rev
- FA: 1200~4000cc/rev

Pilot Steering Unit for FA(M)
The FA(M) flow amplifier require special pilot power steering units: FAPS LS, FAPD LS
There are load sensing steering units whose L and R connections are open to tank in neutral position.
Application
In Large vehicles, a steering system consists of a power steering unit and a flow amplifier
Specification
- Max. steering pressure: 210bar(20.6MPa)
- Displacement: 80~240cc/rev
