Integral Power Steering Unit

Integral Power Steering Unit

Features

• Various integral valves are applied within steering system. (inlet check valve, relief valve, suction valve, shock valve)
• Attachable valve blocks : priority, flow divider, flow control valve, etc.
• Special functions according to customer's request are available: high system pressure, high back pressure, low slip gerotor, low input torque, etc.

Option valve

1. Inlet check valve: prevent kick back phenomenon.
   (In case of the pressure of steering cylinder is higher than one of the inlet ports, instant kick back phenomenon occurs by the returned oil.)
2. Inlet relief valve: set the maximum steering system pressure.
3. Suction valve(anti-cavitation valve): prevent the cylinder vacuum phenomena.
   : prevent the internal cavitation resulted by external forces and the operation of the shock valve.
4. Shock valve(overload relief valve): prevent internal overpressure generated by external forces.
