Application Scenarios

The NG25 size with a 220 L/min capacity is a “powerhouse” valve used in heavy industrial sectors where smooth, linear control of large actuators is required:

  • Primary Metal Industry: Controlling the movement of heavy rollers in steel mills or regulating tilting furnaces.

  • Large Injection Molding: Managing high-speed clamping units and precise injection profiles for large plastic parts.

  • Heavy-Duty Forming: Controlling the slide movement and decompression sequences in medium-to-large hydraulic presses.

  • Marine & Offshore: Operating heavy-duty winches, cargo hatches, or large-scale steering gear systems.

  • Infrastructure & Mining: Managing large hydraulic jacks for bridge lifting or the shield movement in Tunnel Boring Machines (TBM).

Original price was: $8,576.00.Current price is: $3,425.00.
