Rexroth R900617973 4WRZE 25 E1-325-7X/6EG24N9EK31/A1V Proportional directional valve

This valve is a “workhorse” for heavy-duty hydraulic systems where massive power must be controlled with surgical precision.

Die Casting Machines: Used for the precise control of the “shot” cylinder speed and pressure profiles.
Large Hydraulic Presses: Ideal for controlling the main ram movement in deep-drawing or forging presses.
Steel Industry: Controlling the movement of rollers, cooling beds, or tilting furnaces.
Marine & Offshore: Managing large winches, steering gear, or crane hydraulics where high flow and reliability are mandatory.
Hydroelectric Power: Controlling the pitch of turbine blades or large gate valves.

Original price was: $3,774.00.Current price is: $2,635.00.
