Operation

 

The RFD-120-PRV regulates fan speed by controlling pressure drop across the fan motor. It operates in a normally closed configuration in the absence of an electrical signal. This HIC reverses flow to the fan motor to reverse fan direction. It includes open transition spools in the directional valves to reduce pressure spikes during reversals. The RFD-120-PRV 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.

Applications

The RFD-120-PRV includes an integrated proportional relief valve to modulate fan speed in circuits using a fixed pump. It can also be used for fan reversal. Use this HIC for mobile equipment for applications requiring up to 120 LPM (31.6 GPM) such as wheel loaders for purging (de-clogging) coolers and radiators to prevent overheating and increase cooling system efficiency.
