Proportional Directional Valve 4WRZ25W6-325-7X/6EG24N9TK4/D3M - Bosch Rexroth R900775783

A power unit installed far away no longer delivers full pressure at the manifold. The 4WRZ25W6-325-7X/6EG24N9TK4/D3M therefore receives its pilot oil through a dedicated X line, reduces it at the valve and controls 325 l/min nominal flow.

Benefits

• External pilot supply through a dedicated X line, independent of the pressure loss in the working circuit.
• Pressure reducing valve right at the valve, pilot pressure is brought to its value on the spot.
• 325 l/min nominal flow, flow up to 870 l/min, spool symbol W6 in size 25.
• 20.3 kg weight, 350 bar maximum operating pressure, internal return through the tank channel.
• Concealed auxiliary actuation and control at 24 VDC through an external amplifier.

Applications

Such installations are found in rolling mills and press lines with a central power unit and widely distributed manifolds. The dedicated X line brings pilot oil straight from the power unit, and reduction happens at the consumer. The return uses the tank channel of the connection pattern.
