Proportional Directional Valve 4WRZE25W8-325-7X/6EG24N9EK31/F1M - Bosch Rexroth R900746609

A valve moving 325 l/min sends a pressure wave into the tank line every time it reverses. So the pilot stage does not feel it, this version has a drain Y of its own while the supply stays internal and the command arrives as a 4...20 mA current.

Benefits

• A dedicated pilot drain Y stays clear of pressure peaks in the tank channel of the manifold.
• Internal supply saves the X line, leaving one single control line.
• Flow rating 325 l/min, maximum flow 870 l/min, operating pressure up to 350 bar.
• Spool symbol W8, three switching positions, concealed auxiliary actuation.
• Current command 4...20 mA, on-board electronics on 24 VDC, mass 20.14 kg.

Technical data

Applications

The version is used in manifolds with a tight tank line, as found in retrofitted presses and compact power units. The Y line is routed separately and without pressure. Interface pattern ISO 4401-08-08-0-05 makes it a swap for any valve of the same size.
