Off-highway mobile machinery OEMs and distributors can choose from six pre-engineered Hydraulic Integrated Circuits (HICs) designed to provide speed control and reversing for hydraulic modulating fan drive motors in open circuit hydraulic fan drive systems. The program includes:
OVERVIEW
P108 211E
• 40, 80, and 120 LPM Frame Sizes• Variable piston pump or fixed pump circuits• Over-Pressure Protection / Anti-Cavitation is standard• Viton O-rings are standard
Proportional relief valve: • Regulates fan speed by controlling pressure drop across fan motor• Normally closed to ensure full fan speed in the absence of electrical signal• PLUS+1® compliant
Solenoid reversing valve:• Reverses flow to the fan motor to reverse fan direction• Open transition spool to reduce the likelihood of pressure spikes during reversals• Sized to minimize parasitic losses due to pressure drop
Dual shock valve with anti-cavitation checks:• Trims the maximum motor torque by absorbing pressure spikes (shock effects) at the
work ports• Anti-cavitation feature allows additional flow to the motor through the tank port
when motor overruns the pump• PVLP shock valves (from PVG) allow for a compact designCustom designs available upon request.
Variable pump fan drive circuits:
- Provide reversing control and over-
pressure protection/anti-cavitation
Fixed pump fan drive circuits:
- Provide modulating and reversing
control with over-pressure protection/
anti-cavitation

RFD-xx-000• Variable Pump fan drive circuits• HIC provides reversing control and over-pressure
protection/anti-cavitation• Variable pump provides modulation (speed
control)
RFD-xx-PRV• Fixed Pump fan drive circuits• HIC provides modulating and reversing control with
over-pressure protection/anti-cavitation
Integrated and compact design with customer flexibility in mind:• Designed and tested specifically for fan drive systems• Configurable for quick availability
Proportional control allows the engine temperature to be controlled within narrow limits:• Helps meet the requirements of new emissions legislation• The engine can be run more efficiently - improving fuel economy and reducing
emissions
Increased design flexibility and scalability:• Multiple frame sizes that allow you to match to your flow and pressure drop
requirements for multiple machines and their respective fan requirements• HIC valve can be placed in the most suitable location on the machine• Reduce parasitic losses by limiting flow to and from the fan drive motor• The gear motor is shorter compared to a fan motor with integrated valve• Two sets of mounting holes for mounting flexibility (SAE and Metric compatible)

Features (continued) Increased productivity:• Fan is reversible to purge (de-clog) coolers and radiators• Prevents overheating with purged cooler• More power available for useful work when radiator is not clogged
Automatic cleaning sequence programmed using PLUS+1™:• Manual or automatic activation• Reference Sauer-Danfoss ‘Fan Drive Application Block’ information• Service screen below illustrates an example reversing fan drive software setup

This valve regulates fan speed by controlling pressure drop across the fan motor. It operates in a normally closed configuration in the absence of an electrrical signal.
The valve reverses flow to the fan motor to reverse fan direction. It includes an open transition spool to reduce pressure spikes during reversals.
It trims the maximum motor torque by absorbing pressure spikes at the work ports. An anti-cavitation feature allows additional flow to the motor when the motor over-runs the pump.
