Member of the Danfoa Group Fan Drive HICs Catalog Reversing Control This HIC reverses flow to the fan motor to reverse fan direction. It includes a DV15-P5-FD open transition spool valve to reduce pressure spikes during reversals. Internal and external piloting options are available. The HIC 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. This HIC can be used for fan reversal in circuits using a variable pump. Use this HIC for mobile equipment such as wheel loaders...
