PROPORTIONAL VALVE R900700446 4WRZE 25 R325-7X/6EG24N9K31/A1D3M

Application Scenarios

The “R” spool (Regenerative) makes this valve specialized for high-speed industrial motion:

  • Fast-Acting Hydraulic Presses: Used to achieve high-speed “rapid advance” of the main cylinder by recycling oil from the rod side to the bore side.

  • Injection Molding Machines: Controlling the high-speed clamping units where fast cycle times are critical.

  • Die Casting: Managing the rapid shot cylinders where the regenerative circuit helps reach high velocities without requiring massive pump flows.

  • Large Industrial Lifts: Providing smooth but fast lifting speeds for heavy platforms.

  • Baling & Compaction Equipment: Utilizing the regenerative function to quickly close the press before switching to high-pressure compaction.

Original price was: $8,854.00.Current price is: $3,655.00.
