Proportional Directional Valve 4WRZ25E1-325-7X/6EG24N9ETK4/M - Bosch Rexroth R900968023

A power unit with a single controlled axis usually manages without a separate pilot circuit. The 4WRZ25E1-325-7X/6EG24N9ETK4/M uses that advantage, is pilot operated entirely internally and controls 325 l/min nominal flow.

Benefits

• 325 l/min nominal flow without external control lines, supply and return stay inside the valve.
• Spool symbol E1 in size 25, flow up to 870 l/min.
• 20.04 kg weight, 350 bar maximum operating pressure, four ports, three switching positions.
• Concealed auxiliary actuation, function checks are possible without connected electronics.
• NBR seals, HL hydraulic fluid, 24 VDC through a 7-pole (6 + PE) plug to EN 175201-804.

Applications

The valve fits single-axis power units on presses, punching machines and clamping fixtures where the manifold sits directly on the tank. Internal pilot operation assumes that the main circuit carries the required pilot pressure and that the tank line builds only little back pressure.
